The name of the course and the qualification sound more glamorous than they actually are, rescue diver is basically one or two steps from junior instructor and doesn't mean I'm specifically trained for underwater rescue, just that 7nderwater rescue is a big part of the course as its something that's (extremely) good to know if you want to be an instructor.

Called you guys "sharks" in the Navy. You'd pull us out if we got "choked" up in the water. Had roughly 2 weeks with a crash course of combat diver. No, didn't commit to it. Walked away telling the "chief", "sorry just not for me." He chuckled, "be here any time diver."

That was over thirty years or so ago. And no, I never did B.U.D.S. If I had stayed in service would have as part of my advanced training due to going to USNUWC, would have got the Wings & Trident being a s.e.a.l or not.

Again though, years and years ago, would not want to go just run and jump in now. *chuckles* I'd need a good six to nine moths re-training. Not sure I'd be fit even then.

Never did anything as interesting as military diving, 'Rescue diver' is really just a name. You get taught underwater rescue, navigation, how to perform rescue breaths in water as you can't compress the chest cavity enough to pump a heart, shore/boat CPR, wound tending (how to tend broken bones and how to distinguish between capillary, venous and arterial bleeding and treat acordingly) and how to use an AED (though if the patient has seawater on them you can't do that until you dry them out) and the usual talk of "If somebody isn't breathing or is asystole they're already in the worst possible condition so anything you do can't make it worse" and so on. I've not dived for a while due to a bad injury I got a while back as I don't want to be a liability to others, or the guy who complains on the boat, I couod do recreational diving without much of an issue but making it a career wouldnt work out as an instructor has to be as agile as possible in case there's an emergency underwater.
Hope that doesn't sound too preachy, but it's why I decided to go with a more acedemic (though still practical) career instead. Dream job would be to operate unmanned submersibles. Previously it was saturation diving (you know, where you spend a week in a pressurised tube after doing a few dives) but that's definitely off the table now. If I can't get into the water physically I'll do it via a long cable and screen.

Yep, all sounds like what our "sharks" did. In simple terms "they got folks out of the water, saved lives". Combat diver course was fun, what I had of it, merely the practical. Other divers tried ripping your gear off you. You had to focus on mission, stay calm. They kept adding stressors, anxieties ... "stay calm".

So yep, walked away. I joke and say those in that field are nuts. In fact they get psych evals regularly and are some "stable" folks. I couldn't have done it then and for sure wouldn't now. Nope, I'm not Superman thanks. :)

The ocean at Virginia Beach tried to eat me once, and I would hate to have been the person who tried to save me from that. By the time I popped my head out of the water, I was as hysterical as I've ever been. Was a strong swimmer back then, but my god, you think the sea has you, you will freak the f out.

Basic swimming class I had back in the 60s, even then they taught us that if you don't go about it right, one drowning person will become two drowning people, or more.

On a very slightly similar note, I had a group of coworkers once who were all members of a local rescue squad. From hearing them tell about their experiences with people, I learned to really admire and respect anyone who goes into a field that is dedicated to saving the lives of others. What would happen if there were not people who could do those things? I'm sure they all deserve more gratitude and more compensation than they get.

One time out in Montauk I decided to buy a Boogie Board because the waves were Crazy due to a Hurricane that had passed. I had the ride of my life but got slammed head first into the sand, rolled around and bounced in the surf caught in a rip tide. Long story short I had sand in every orifice for a week~!

As for Mooch, I feel like I've insulted a sacred cow. He definitely seems experienced I just shy away from people who ask for subs. Suggesting that they donate through patreon is a better way to go about it, or at least I find it less of an on your face way to ask for donos, the whole "like comment subscribe" overlay tends to be less in my face but that's because it's used so regularly I kind of tune it out. I don't think that he is wrong on what he's talking about, he seems well experienced, although I wish he went into even more detail, even if I only understand half of it or need to do a few days of reading to understand most of it. The bundle of notes on the livestream was also something a bit alien to me as I'm used to people like Louis Rossman and other technical you tubers being able to recite stuff immediately off the top of their though even when it comes to stuff I know really well I occasionally forget important details when put on the spot, like in the middle of doing a livestream and reading through comments as well as talking about something I know well. What does/did he do other than or before reviewing cells/batteries anyway? Electrochemist? Electrical engineer? I'm genuinely curious.
He lives in a small apartment in Manhattan. There are no cows in Manhattan I don't believe... or if there ever was one and it was a sacred one, then prolly it must've been killed during the attack.

Him asking people to subscribe on YouTube is understandable for the fact that he really needs that extra $$ for getting more different batteries so that he can test them and for getting enough plywood to hold all his test equipment in such a tiny room that also happens to be the only room that he can use for this stuff. He already is on Patreon.

He went into quite a lot of detail about many different battery related questions actually, when he was still answering them during his "Power Hour" live streams. In the comments section of his last live stream you can read the reply he wrote when people started asking why he hasn't been back on there yet. On Reddit he is still actively replying to members there it seems: https://www.reddit.com/user/Mooch315

Originally he got interested in battery technology a very long time ago when he got himself involved with the RC community. He mainly designs battery test setups and battery test procedures for clients in the tech industry, and he has worked for Hewlett Packard and for the US Army. I guess it's fair to say that his knowledge of and experience with batteries and battery related tech is unfathomable because he's been being a battery FREAK for a quarter of a century or thereabout, and he is also a vaper. He deserves all the credit for calling out "rewrap companies" like Efest who were (and a lot of them still are) printing hugely exaggerated ratings on the battery wraps of batteries that they rewrap. In the particular example of Efest, they were putting a 60A rating on the LG HG2, which is only a 20A cell.

None of the so-called "reviewers" can hold a candle against him when they start to talk about batteries. Look at that guy called HKJ on budgetlightforum.com, for example, who reviews batteries and battery chargers on his own personal website lygte-info.dk and who often is thought to be experienced especially when it comes to battery chargers. Specifically, look at his pics that show temperature recordings of all the battery chargers he has "tested". Next, look at "Minding Your Mechs" video episodes by Mooch on YouTube and learn what factually happens if you point a heat detection camera at a reflective surface. That's right... the reflections skew measurements so heavily that you really need to use matte black tape in order to prevent that from happening. HKJ's heat detection pics show some parts of surfaces on various different battery chargers getting way hotter than 60 degrees Celsius. It doesn't take to be a rocket scientist to know that these measurements by HKJ are too severely flawed to still be called useful in any way whatsoever. Because, as a matter of fact, 60 degrees Celsius is hot enough to start burning a person's skin, which everyone already knows just never happens when you touch such a charger, even by a long shot. That's the difference between a true professional like Mooch and a newbie whose level of "credibility" is merely the result of more newbies on the internet persistently propelling newbie nonsense like that. Sorry for long response, but it needed to be said...

Kind of reminds me of the underwater fights we had and the pranks we played (such as circling back around someone on a shore dive and as soon as they got up we grabbed their legs and pulled them back under) but we always did it in a safe manner. Mainly just knocking the masks off of people who we knew wouldn't take it a bad way as being able to clear the water from a mask which has been knocked off underwater is pretty important and it happens more often than you'd expect, especially if you get too close to the fins of someone in front of you, that usually results in you losing both your mask and regulator at the same time. Stuff like that kept us sharp. Though we weren't military divers, or technical divers, just recreational divers. Only 'rescue' I ever had to do (other than the mock rescues) was for two divers who got caught in a current and were getting pulled into the middle of a peninsula, that was just a half mile run/jog in a semi-dry suit with someone else then the other guy (more senior than me) swam in and pulled on their (relatively) fast moving divers buoy to get their attention. They'd have probably needed a boat rescue if we didn't get to them but it was in a small peninsula so the boat rescue would have probably just been one of our guys in a RIB (Zodiac) rather than the coast guard, so not a 'serious' rescue.

I had the ride of my life but got slammed head first into the sand, rolled around and bounced in the surf caught in a rip tide. Long story short I had sand in every orifice for a week~!
I got caught in a rip-tide myself. I was warned "there's a rip-tide there" but fifteen year old me thought that would be fine.
I had to swim harder and faster diagonally until I got to shore. One of the only times I've really panicked, feeling like you're being carried out to sea is a really scary thing.

Just wickin ..... :cool:
Yep. On that note my package of Kevin Bacon arrived today.
Firstly Kevin Bacon is easier to work with than cotton ball and comes nicely sized too. You can pull it apart easily too, cotton balls feel so delicate that I used scissors.
There was an odd taste at first. Similar to the cotton ball but definitely not as pronounced. Maybe the cotton ball wick did taste awful to begin with and I've forgotten it as it went away quickly (kind of the same as taking something illicit, throwing up everywhere then having a great night out) and tasted fine after. I'll have to do at least one more cotton ball test and then back to cotton bacon to give a conclusive answer though. I will say that cotton bacon seems to have more flavour than cotton ball though maybe this is just placebo.

I didn't have time to get scared because I was battered and bruised big time~! No Lifeguards at the resort on the beach either so no one knew I was in trouble. Like you said swim sideways and my GF and her Mom never knew anything until they saw how much I was bleeding from the sand rash~! I had to walk so far back to where I entered the water after I was dragged out enough to actually try swimming again.

Oh I was in my 40's when this happened also. LMFAO

I have used a variety of cotton that came with RTAs but not sure what they are. I have also used regular store bought cotton balls (only for quick flavor tests in a RDA... test one, rewick, test another... quick and dirty) I did boil and dry them first. I wanted to try "rayon" and got the cotton version by mistake (they are both sold as "cellu-cotton" on amazon) It does seem to work fine. Then I got "rayon" I use both (depending on the RDA/RTA) Both are really cheap and you get tons of it. One specific RTA likes rayon (it has small juice flow holes) but my other RTA tends to leak so cotton works better. Just keep in mind (like was mentioned) that you have to stuff rayon tighter in the coil than you would with cotton.
I'm surprised nobody mentioned the "cellu-cotton" so I wanted it bring this up.
Here's the cotton version:
https://www.amazon.com/Graham-Cellu...=1&keywords=cellucotton&qid=1632095243&sr=8-6
Here's the rayon version:
https://www.amazon.com/Graham-Cellu...=1&keywords=cellucotton&qid=1632095243&sr=8-3
I am in no way an expert about this... still learning myself.

Thanks. I'd seen cellucotton referred to as rayon in a few videos (I always thought rayon was a synthetic cotton substitute) and apparently it works well.
With the Zeus X RTA it has top airflow directed down a reverse chimney which blasts the coils and cotton with air. I bought it just to match up geekvape products and because it was reasonably priced (not so much if I want to buy 3.5ml glass due to a completely stupid law that limits vapes to 2ml and nicotine containing juice containers to 10ml (they just sell them in packs of 4 now or sell larger 0mg bottles along with nicotine in PG:VG that you add after) as for vapes you just buy the bubble glass separately. Granted the straight glass seems to work well for me as it means that the mod hits the ground first if it tips over rather than the glass, unless you get really unlucky.

I've had some issues wicking (cotton bacon prime) as I tried the whole Scottish roll thing and it usually led to the cotton not feeding through the coil correctly, bunching up on one end and then the cotton in the coil burning up so badly that you could practically touch the cotton and it would break into two pieces after 300 or so draws. Pulling the cotton through the regular way seems to work fine up to (and above) 1000.
I have some muji pads ordered from ebay. Getting a seller that didn't use the dumb AF automated age verification which doesn't work for non-English drivers licences took a few checks. It's cotton. [Tangent warning] I can literally buy a crack pipe set in a presentation box (even labelled and sold as "crack pipe set") with no age verification needed, not from ebay but still from a reputable supplier. Not that I would want one, it's just a comparison as ebay won't allow you to buy anything 'vape related' even if there is no nicotine or even vape juice in the product you buy. For example, cotton bacon or spare glass. The issue for me is that I end up using amazon which I don't really like as they treat their workers pretty badly. Amazon also mention age verification requiring ID on delivery but that hasn't happened yet and isn't an issue as I'm in my late 20s and can remember being able to buy cigarettes at 14 because the legal age to buy was 16, though not many places cared even when I was 18 and I remember 13-17 year old people buying cigs without a problem.

In a similar vein, ...

Work as substitute custodian for county schools. Know two full time custodians, possibly four what rub snuff kids present or not.
Am told I'm not to vape, even if no kids present & in an adult restricted area.

No one says a thing to those rubbing snuff and it's patently obvious they do. So, yes, I do vape. Yes, I'm discrete with it but if I'm on a lunch and in said adult area, no kids, I enjoy.

AFAIK, this is a policy only. No tobacco use in schools. Well, I'm not using tobacco technically. As to letting kids have or use my gear, big NO, full stop. Buy them vape stuff? NO. Tell them vaping is good? NO. Glorify it? NO.

Life is so absurd to fill itself with stupid double standards.

Like I said, I use both cotton and rayon (really depends on the specific RTA/RDA) Most of them you can use either... a few prefer one over the other (it's hard to call... still playing around with that) The real trick to wicking is to use the right amount for the coil (and then how to deal with the "tail ends"... that's the real art) Always "prime" the coil/wick with juice first. With RTAs, even after priming and assembling the tank, fill and wait awhile before vaping. Maybe even do a few "primer puffs" (draw air without firing the mod) Start lower wattage than expected at first and then wok your way up.
Peace out. Vape on! (oh no... the people on that "other forum" will know who I am now... no worries, never had issues with anyone except a few select snobs that tricked me into hanging myself)
 
Forgot to mention... Jai Haze (YT video reviewer) uses Egyptian cotton from some old rug he has... what a nut!
That sounds interesting.
Personally I've always been interested with the wicking characteristics of asbestos. I mean you simply can't burn it. If it wicked well it would make for the perfect wick.
So long as you ignore the lung cancer and mesothelioma.
Glass fibre loft insulation might work but apparently it's also a pretty good irritant of skin and your mucous membranes. Can attest to this as I got covered in the stuff when the kitten climbed up the ladder into the loft and I had to go after her on my belly so I didn't go through the cieling below.

Jai Haze is an asshole who stopped dealing with Vaping when he couldn't make anymore money off it. Even started showing his employees tits off trying to get likes when NJ Shut him down. So much for advocating huh?
 
Update
Got some muji pads. 30 of them.
Been trying the Scottish roll with them but I might be using too little cotton. However overall these seem to be better (and a lot cheaper) than cotton bacon prime. Cotton bacon prime lasted about 300-1000 draws at 75W average.
My first muji lasted 1200 before I started noticing a loss of flavour. When I pulled the cotton out of the coils there was very mild scorching, some of the cotton bacon had burned through. Excellent wicking too. With cotton bacon I had to flick the tank and wait for some bubbles to rise after about 3-5 draws. The muji pads seem to have a slight dry taste but no burning cotton taste after 6+ quick inhales.
It could be that I'm using less cotton with the mujis and that the RTA (zeus x) I'm using is a 'less is more' type.
Cost wise they're a big win too. I got 30 of the new larger ones, (30 seemed to be the optimal amount to price on ebay due to shipping being factored in to each quantity) for the same price (maybe less) as one pack of cotton bacon prime.
It's a subjective opinion but these seem to work the best so far with unwashed cotton balls ranking lowest (but still completely useful) cotton bacon in the middle and mujis ranking best.

One thing to note is that I have switched juices for now as the supermarket is out of stock for the ones I like which seem to be sweetener heavy (and also really cheap) but I ran some 9mg cherry liquid through the mujis that I also ran through the cotton bacon and not only could I just about taste the cherry it didn't turn my teeth black (which it did with cotton bacon) so they seem to be the best so far but further testing is needed and all testing is subjective and for one RTA only.

I didn't realize you are full blown DL (cloud chaser?) I mostly do restricted DL but... very soon trying a dual coil RDA (that should be interesting) I never count (or set puff counter) but 1000 draws at 75 watts on the same wick(s) is great.

I usually vape between 70 and 90 Watts. I suppose it would be considered DL vaping, mouth to lung isn't something I'm used to and it doesn't feel natural to me. I smoked cigarettes for about a year when I was about 19 and just stopped one day, I bought maybe two packs in that year and the rest I just rolled by rolling a cigarette for a friend and one for myself. That would be my only experience with MTL smoking. More often I would use a hookah and since the smoke is cooled and its constantly heated it is really a DTL way of smoking and when I did that (a few years ago) I usually added vape juice to the tobacco mixture for more flavour. So from mainly consuming tobacco from a hookah I would be more used to DTL with large quantities of smoke/vapour (a hookah really does generate more of a vapour than a smoke as it uses tobacco soaked in what I think is glycol, glycerine and flavouring then heated but not burned with charcoal) and when I started vaping I would just inhale until the vape itself cut out. I started with a 'single use' vape pen that was on sale for next to nothing and they're far from being single use as you can recharge the LiFePo cell with a power supply and refill the tank by drilling a small hole in the tank with a press drill/hand drill and covering the hole with tape after refilling. It lasted for a out 2 weeks before the coil burned out. After that I got a Smok vape pen V2 and found that the coils burned out in about 2 days and at about £2.75 a coil it was way too expensive to use compared to something I could wick myself. Both the 'disposable' vape and smok pen usually did the 8 second cutout whereas I only inhale for about 3-4 seconds with this at 75W.

As for cloud chasing, I wouldn't say that's really an activity I'm interested in. I enjoy blowing smoke/vape rings but I'm not on a mission to create the largest clouds possible. However I do tend to chain vape when I don't have anything else to do with my hands and focus on. I usually use 6mg vape juice or 12mg as I find that nicotine is a handy stimulant when I'm doing college work (nicotine isolate isn't as addictive as tobacco as tobacco also contains naturally produced MAOIs which prolong the effect and increase withdrawal symptoms) and stuff though it's almost always diluted with CBD e liquid (completely legal here, not sure what the laws are like in the states) as I suffer from chronic pain (I was supposed to be getting surgery but then the pandemic happened) and it helps a bit but at this point I'll take anything that helps.

The only thing I don't like with such a high wattage is the tongue and throat splashback I get if the tank is completely full. I assume this is caused by pressure but with a 3/4 full tank this doesn't happen. Hot splashback worries me a bit as hot liquids hitting your mouth and throat can cause cancer later in life, at least this is something I've heard about very hot coffee causing mouth and throat cancer. As such I try to avoid it.

Sorry for the long post but that covers pretty much everything.

Think on average I do a meager 24 watts or so. Use mostly mechanical mods so I don't pay any mind to watts, least not too much so. I do DL & RDL. Kind of walk a middle line of flavor/cloud chaser. Like using single coil RDA most often. Got away from tanks & rolled into squonking. "A squonker's life for me t'is, argh!" :)

This RDA she be a tricky one. Youse might t'ink she only be an MTL one. Nah, youse get fooled she be a all around any style youse wanna use 'er for. It take a little time being used to her, but once you do, you see. :) If you want a tip for her.

Don't apologize... very helpful knowing these things. So you liked doing the "shisha" hookah thing (I have younger friends from "the bay area" in CA that love that) It's still tobacco but at least it burns cooler (and flavored... I can see the appeal)
P.S. I never fill tanks/pods all the way. Seems to help leaving some air in there to minimize pressure/vacuum issues (don't want to get to techno, but there is no such thing as a vacuum... just different pressures unless you are in outer space) Kinda like there is no such thing as cold... just different amounts of heat ;)
I wasn't implying you want to "chase clouds" like in competitions, it's just what I call DL vaping in general. Sort of like how some people that vape low wattage MTL are called "tootle puffers". I'm in the middle somewhere between those.

Sorry for the long post but that covers pretty much everything.
If you dilute e-liquid that contains nicotine with CBD e-liquid, then to be on the safer side of things you should avoid vaping it too long after you mix the two together. AFAIK a slow chemical reaction tends to occur after adding nicotine to cannabinoids like CBD and terpenes commonly found in CBD e-liquid. Especially when it comes to the wide variety of terpenes that are typifying of "broad spectrum" and "full spectrum" CBD products, this could cause side effects that may potentially become harmful with prolonged use. In fact, a lot of terpenes haven't been well studied, their long term effects on health still remain largely unknown to date, and, a typical (legal) "broad spectrum" CBD product can contain more than 100 different terpenes so, there's always more than several terpenes in there that do not belong in the "generally recognized as safe" category. (Maybe one day they might all wind up in that category, or they might not... at least for now, it's mainly about speculation, no matter the fact it's legal, as the process of lawmaking isn't synonymous to the scientific method of course.)

Manufacturers of CBD products are very often trying to mislead with marketing descriptions like "whole plant" or "natural". The reality is that the purest (and safest) type of CBD is called "pure CBD isolate", which is both 1/ expensive and 2/ not exactly very potent due to lacking what is known as the "entourage effect" from all the various terpenes that, although they vastly help to improve the potency of CBD as a result from this effect, might not be equally as harmless as pure CBD isolate. Needless to say you also need to 3/ factor in how pure is "pure", as there exists no linear relationship between, e.g., "99.6% pure" or "99.7% pure" and the level of harm that may be caused by each different type of impurity.

I've used CBD products myself, regularly for more than a year, in the form of sublingual tincture and in the form of vaping CBD e-liquid, also including fairly high strength (600mg CBD in a 10ml bottle of e-liquid) diluted with regular e-liquid at 3mg of nicotine strength in an RDA, that I vaped on a single battery mech mod at 0.11 ohms dual coil, and that, with the battery fully charged, translates to ~129 watts after the voltage sag of the battery. To be more specific, I was using loudly crackling 27/36 Ni80 alien coils at 5 wraps 2.5mm─same specs as the ones that Mike (m.terk) also sells on his website BTW─in the 25mm Kennedy RDA, a typical flavor chasing setup the flavor quality of which IME is nothing short of exquisite. Using Cotton Bacon 2.0 the way I have described in my 2nd reply to this thread and getting no burned taste of any kind, abeit I am well aware that can still happen if I try to wick it up too impatiently, in which case it'll only get MORE time consuming because, THEN, I just end up having to redo it yet again thinking that smoking normal cigarettes was so much less of a PITA... 🤣

That being said, I stopped using CBD altogether after I switched to using dōTERRA Copaiba (Copaifera) Essential Oil, that can not (!) be vaped, but that can be used as a sublingual tincture if using not (!) more than 6 droplets per day. 1-2 drops per day is usually sufficient for me, which means that I use less than one 15ml bottle per year. The main important ingredient is β-caryophyllene, a natural cyclic sesquiterpene that is generally recognized as safe.

Not heard much about β-caryophyllene/copifera. The only thing I've read is that it increases tolerance to cold temperatures. I'll look into it more and see what medical research there is into it. As for the CBD I use, I use isolate as it costs half as much as distillate. I would have thought distilatte would be cheaper but the price is probably due to it being a bit more effective, "weeed bro" and "natural", unless it has double efficacy I wouldn't be willing to pay double the price. As for terpenes reacting with nicotine, maybe. I've wondered whether nicotine base or nicotine salt would be more reactive for one. Nicotine base would potentially bond to acidic compounds in a liquid in while the benzoic acid could be neutralized by basic compounds in a liquid. Or there could be side reactions that nobody knows about yet. I would love for someone to do GCMS, IR spectroscopy and other tests on before and after mixing samples and see if there are any concerning chemical changes (involving terpenes) the only source I have on CBD (alone) reacting with nicotine and being bad is some guy on YouTube. I asked if he had any further information as neither nicotine nor CBD (alone) are particularly reactive and if they could give any further information and got a reply along the lines of "You know this is YouTube, right?" so I assume they were spouting third hand information as gospel in their video. You however have gone into much more detail on the subject.
I'll have to try your method with cotton bacon. I'm getting pretty good results with mujis by stripping off both hard layers, cutting 2cm (3/4") spreading them out a bit then rolling them up. Much better wicking than my experience with cotton bacon prime based on the lack of burnt hits and the really big bubbles rising up into the tank. With cotton bacon prime I had to flick the tank and wait, but I might have been using it wrong or maybe its better suited to dippers rather than tanks. I got about maybe 300-600 drags from cotton bacon whereas I get about 250-1200 from mujis with the large range being due to me using too little/too much and not rolling it up properly so some of the cotton catches and doesn't pull through, making the wick uneven. Both are problems that I can fix with practice.
Don't apologize... very helpful knowing these things. So you liked doing the "shisha" hookah thing (I have younger friends from "the bay area" in CA that love that) It's still tobacco but at least it burns cooler (and flavored... I can see the appeal)
P.S. I never fill tanks/pods all the way. Seems to help leaving some air in there to minimize pressure/vacuum issues (don't want to get to techno, but there is no such thing as a vacuum... just different pressures unless you are in outer space) Kinda like there is no such thing as cold... just different amounts of heat ;)
I wasn't implying you want to "chase clouds" like in competitions, it's just what I call DL vaping in general. Sort of like how some people that vape low wattage MTL are called "tootle puffers". I'm in the middle somewhere between those.
Yeah I get what you mean, filling the tank all the way does seem to cause splashback issues. Not sure whether it's caused due to increased pressure though surely a few cm isn't enough to increase the pressure of the liquid too much or suction increasing when a tank is full. As the airflow is directed down at the wick (zeus X) from top airflow ports I can't see how this would affect things either but something is causing it, possibly a mixture of both things.

CBD acts on the Endocannabinoid System (ECS) of the body in a fundamentally different way than β-caryophyllene does. CBD therapy relies on a cascade of effects (plural) that, in a nutshell, if some certain criteria (the various different impacts of which have not yet been well studied) are met, causes it to bond to both the CB1 and the CB2 receptors, only INDIRECTLY. The "indirectly" here helps to explain why CBD tends to have a relatively low potency for many, or why, for it to be effective, so many people need to consume tons of "high strength CBD", much to the point of being way too costly to be sustainable. Ergo, it is only logical the fact that clever marketing has created a new avalanche in recent years, turning the entourage effect into a cash cow by hyping it up as highly as possible or even higher. Although the entourage effect is very real and therefore it does have great potential deserving of future scientific research, when it comes to the relentless, consumerist, CBD marketing that's been going on, the silence about the particular subject of potentially harmful side effects that may result from long term regular consumption of high doses of the terpenes that either are or may be necessary to achieve this same entourage effect is deafening enough to notice an elephant is standing in the room. In any event, lacing CBD up with as many different terpenes as you can get a hold of is nothing short of quackery, and, the quackery works because people are pitfalling, in bunches no less. Unlike CBD, β-caryophyllene binds to the CB2 receptors DIRECTLY. (β-caryophyllene does NOT bind to the CB1 receptors in any way.)

About Cotton Bacon Prime. Try Cotton Bacon 2.0 instead, and try prepping it like shown in the video that I linked to earlier, but also try to avoid grating it with your fingernails... gently peel off the knots instead of trying to keep scratching. So avoid scratching and roughing it up, try to just rub in one direction on all sides of the stick of cotton. You may also have to loosen up (slightly!) those specific parts of the stick of cotton where the fibers are too densely packed. Get a "cotton hook" (pic below) and use it to, after you pulled the wicks through the coils and also after you bent the trimmed tails of the wicks down into the (topmost part of the) juice holes of the build deck, stab vertically down though the tails of the wicks in multiple different spots to loosen the fibers up even further still. Nudge it to get it to comply. Learn to empathize with the cotton. :p

It's not about juice... it's about air. Air easily compresses/expands but liquids don't. Having some air (headroom) allows pressure/"vacuum" to equalize easier (OK, now I've even confused myself) It just works and helps.

I understand what you mean and was thinking about it the other night. As the drip tip is locked into place it moves down 1-2mm which might be enough to engage with the silicone gasket and push some liquid up into the wicks/wicking chamber. There must be a very delicate balance going on for this RTA to function. I've seen some reviews complaining about serious splashback and it makes me wonder if they got one where the tolerances were slightly out and liquid went up through the wicking well and into the chamber.
When I think about it more R&D probably went into the RTA than the mod, yet the mod costs more. Airflow has to enter from the top yet still pull up vapour, the liquid in the tank can't leak out from anywhere (it hasn't leaked on me once) and it also has to be compact.
An interesting top airflow rta would probably be one that brings the air right under the wicks and then up, essentially working like a bottom airflow RTA but with the air coming in the top. It would probably be really bulky however.

Speaking of top and bottom airflow, is bottom airflow really that big of an advantage in terms of flavour? The ones I've seen pretty much use metal pipes directed at the wicks from below. Though maybe this was for an older RDA.
The only thing I've used with bottom airflow was a Smog vape pen V2. Not something I would recommend. Coils need changing about every 2 days and the taste is almost nonexistent. I used only liquorice flavoured juice in it and when I switched to this RTA the difference was so large that the really, really strong liquorice flavour nearly made me throw up.
I really feel bad for people who know RTAs don't exist. I was in a vape shop because I happened to pass by and bought some of their bargain bucket liquids (almost all were awful) as I was waiting on a delivery. They were selling pod vapes to some people and I felt really bad for them as he was selling them a pod vape for about £30 and they'll be paying about £3 per refillable pod after it burns out after I day. Prebuilt coils and shoelace cotton would be cheaper than that in the long term. Took a fair bit of self control to not cut the guy off and say they should consider buying something rebuildable, which I doubt that place sells as their prices are sky high and its good business to get people coming back for coils/pods.
