At the advice of a Madvape retail rep I went from 1.5ohm dual coil carto to single 3.2ohm carto. I've got to tell you, the single 3.2 on my Twist and Spinner, at 4.8v, is the way to go. I never would have thought but I was practically burning up the dual 1.5ohm and didn't know what to do. The 3.2 ohm works GREAT. Plumes of smoke and a great TH, all for $1.59 each, you can't beat that.
