I have two TC
mods but don't like the "regulated" experience so continue using mechs most of the time. My outdoors/work
mod is a regulated TC Invader mini 50watt, I've not noticed a difference in coil life/gunk build up but run pretty hot at 385F (
Titanium wire), which might be why. With my NETs coil buildup/gunking isn't really a problem, it's wick saturation where after 10 - 15ml of juice the wick has trouble "wicking" properly (
fast enough), and flavor begins to drop off/mute. Normally the coils are only lightly soiled at that point. TC -VS- mech seems to make no difference when it comes to wick failure as far as I can tell.
EDIT: Since I don't really care for regulated/TC mods and only use them when out working I'm still a novice when it comes to using TC, someone with more experience in their use may be able to obtain better results.
