I currently use 1.5 ohm joyetech atties in my UFS. I enjoy them for the most part but miss the heat I get with my Provari running at 4.4-4.5 with them. I would prefer to buy atties instead of using RBAs. Anyone know anyone that sells atties at 1.1-1.2 ohms? Or any atties that might produce more heat at whatever ohm?
