Not using the Boreas yet.................but got hold of the new SMOK TF-RDTA and tried the pancaking overlapped wick in bottom and massive leaks. Then rewicked it, poked a bit of the tail thru the juice holes and pancaked
(any remaining tails touching or slight over lap) and bingo no leaks, just shut off the JC pop top fill and open the JC.................but one thing that did happen, although worked all day and evening without issue, went to bed left rig standing up everything open, air, JC etc and woke up to a slight amount of juice on table...reason....a storm with LOW pressure went thru during the night lowering the ambient air pressure and created a slightly lower outside air pressure than that most likely in tank.............almost a guaranteed leak. Now today with outside air pressure stable
(low but stable) no issues with leaking and have done nothing to Tank..........
It might be that "some", not saying all issues with the Boreas leaks could be due to varying air pressure combined with maybe a bit of (or lack of) attention to detail, O-rings.............and maybe the larger size tank (8 ml) which would require a bit more "vacuum" inside the tank to maintain equilibrium with the air pressures versus the smaller 5 ml or so tanks...........more liquid creates more downward pressure on juice flow holes.....I'm willing to bet this is going to make "Just the right wicking necessary" or maybe just a bit more wick (in juice holes) to compensate for this and varying atmospheric pressures, temperature swings, etc.......
I know I increased the total amount of cotton in my other RTA's a bit
(made it a bit difficult to reinsert the decks) so that there was more juice being held in the chamber
(still must be very careful about fluffing the wick tails in juice slots for feeding the coils, can't restrict or pak too tight)..............on one RTA (SMOK TF-G2) it went from ok flavor to fantastic flavor, same coils, it did result in a slight, very very slight additional restriction (maybe 10% or less) of the air flow. But the difference in flavor was massive.......and it sure didn't hurt the other RTA (Griffin 25) either.....none have ANY leaks and I've run them as high as I can stand 60-80 watts and chain vaped 8-10 times one after another.......no dry hits (but I was coughing and dizzy as hell!), the flavor did began to fall off towards the end, but an RTA can only supply so much juice............the RDTA's on the other hand can supply way more potentially.......
(P.S. Running the Smok G2 and Griffin 25 with SS 3mm Clapton coils in TC mode 50 watts at around 425 deg)
Just my thoughts on the matter........But I'm no "expert"
( drip under pressure=expert) and might be way off base....
Still thinking about getting the Boreas, the extra juice capacity and flavor boost of the RDTA WOULD be nice......definitely want to look at the Merlin.
