I don't need to justify a damn thing in any of my vape-gear purchases.. Over 4 years ago, I spent around $255.00 each and every month on cigs / cigars for many years. When I made the decision to start vaping a little over 4 years ago, I saw it as a reduced-harm substitution to tobacco smoking.. I figured that I didn't deprive myself of tobacco, and the $$ it cost, why should I deprive myself of vape-gear for the same cost?
It's great that you can afford to set aside such generous vape budget. I sure am jealous.
It seems reasonable to assume that it will take some community experimentation to discover power level/build combos that are able to work well with temperature protection. Brandon from Evolv spoke about high temperatures producing a superheated layer of vaper that forms next to the coil which prevents the coil from being cooled starting at 41:11 in his Vapour Trails/Haze Hour's Dec. 4 interview. This would likely mean that at some point temperature protection will do nothing but throttle back user-selected power because air flow and wicking technique won't provide enough cooling to overcome the superheated layer of vaper produced by high power going to the coil.
I see. So it's back to air flow and wicking once again, temp-controlled or not. Like you mentioned, more will be revealed as the community experiments with different builds and settings. And I was just beginning to wonder, for experiments sake, about how I would personally build temp-controlled setup in order to achieve high watt output.
I would probably take a 30mm RDA and throw on a super-macro 'double' Clapton with wide open air flow. 'Double' Clapton is where you wrap a second layer on top of a regular Clapton. That's just what I call it. There is probably a different term coined for it. It seems to maximize juice contact area, bring out different flavor notes as 2 outer layers heat up at different rate, and produce coolder vape. Would all of that even matter at say 100+ watts?
