@Carambrda , yes,,, some day I will dive into that (not ready yet but would like any advice on that subject)
Well I'm not an expert builder by any means, I first and foremost build coils for the goal of improving
BOTH the flavor performance
AND the
feel of the vape, and to experiment with these factors. (For how I like to vape, these 2 different factors are so tremendously interlinked in every way that I'd say they are pretty much inseparable, at least to me, so it is about warmth, wetness, density, saturation, texture, speed of inhalation and level of restrictiveness as much as it is about flavor─and about depth of flavor.) Most other builders I've seen are more concerned about the visual experience, i.e. the aesthetics part of the coil building equation (art/ marketing, marketing/art) and about showing off their own skills with regards to the difficulty level that is involved, much less about the actual vape experience, unfortunately. What this also means is I don't futz around with things like rectangular wire or extremely thin round wire. (Above 40g is already much too thin for it to serve a real purpose when it comes to trying to achieve my aforementioned goals of looking for improvement.) Please don't get me wrong... I like a good looking coil build, and also I like many forms of art. What I don't like are people who try to disinform about the performance potential (and/or lack thereof) that can be had with certain coil types, and who aim to turn that disinformation strategy into a lucrative business model. It is detrimental to those who just want to learn how to experience a better vape and want to share that experience, or knowledge.
In addition, I never use stainless steel wire types in any of my coil builds. SS 316L wire is multiple times less resilient to dry firing and dry burning than Ni80, and, watt for watt, it ramps up slower than Ni80 if the volume of the wire strand (i.e., half the diameter times half the diameter times
π times length) is kept the same. A lot of people keep referring to the mass of the coil when they discuss the rampup time, but the correct variable to want to use for that is the volume, as the mass is actually irrelevant. But anyway, as I'm not allergic to nickel, SS 316L adds nothing for me. Rather, all that it factually does is it just makes the coils wear out in next to no time. TC (temp control) is a pure waste of time because, in wattage mode, you should be able to adjust both the airflow setting of your RBA and the strength of your draw, and, if the type of RBA you use is an RDA, the importance of learning first how to avoid getting dry hits in wattage mode is both undeniable and trivial. With complex coil builds tailored specifically toward being an improvement in the vape experience when compared to simple coil builds, TC doesn't actually even work right. The surface temp of the core wire strands cannot accurately be measured, as it differs from that of the deeper regions inside the metal, significantly. The increased speed of evaporation and of the airflow that collides with the
complex coil is why this is so. (The combined effect caused by these factors carries the heat away from the complex coil's surface at a rate that is faster than the rate at which heat gets transferred inside the metal itself.) Finally, I'll also add that the metallic taste of Ni80 goes away permanently if you stick to premium quality Ni80 (grade A) and you dry fire your freshly built coils, adequately before the first use.
