I have a new Knight Rider on its way and I have a couple questions from those that have used them. First, I usually use Kanger 2.0ohm horizontal coil cartomizers...how are these going above a standard eGo at 3.3v? Also I have some eGo Vision/StarDust coming, what voltage can these go to? Any help with your experience would be greatly appreciated. I know I need to play around by gradually increasing voltage to find the sweet spot, just looking for advice from others experiences.
