Right now I am using pre-built coil because thats what my tank is. I do however have a rda that is running a .5ish kenthal 22 guage single coil.2. Tell us your coil specs (like material, diameter, pre-build or not, Clapton style, ect) if you have coil builds experience? If not, tell us why you choose to skip rebuilding.
Leak free is something that I would love to experience3. Tell us which feature of the tank do you like best
