I agree that .4 to .5 is ideal for TC on the mini with SS (around .2 for Ni200 and .4 for Ti).
In my opinion, only my opinion, I don't think TC was originally meant to be used in multiple coil setups. I would never tell anyone how to vape, to each their own, but multiple coil's can introduce so many more variables into the TC equation as to cause issues with accuracy.
Agreed wholeheartedly. When the original TC concept was brought to market in the DNA40, I believe EVOLV was targeting single coil RTAs & RDAs. I also believe this was made evident by it being "only 40 watts". I can't believe anyone was thinking that those insisting on 24awg multi-coils would WANT to vape TC.
