So, build #3 is rockin in my BV2. Claptons (too lazy to make my own, bought UD 26AWG*32AWG*5mm), 5 wrap 2mm ID and running at .5ohm. It is kicking out serious clouds, but spits more than it vapes. Not sure if I just don't like more complex builds (24G twisted kanthal is just too hot, .5mm twisted Ti isn't bad, but not great...) but I will probably be sticking with 6 wraps of 24G kanthal. Anyone tried vertical coils yet?
