I own 3 kafun 3.1's and a Russian and have had a genny and the perfect rta is something I have been searching for. 2 of my kayfuns are modded and can kill the russian, Now I just got a Fogger V4 and while I hate to use the term "kayfun killer" but this Fogger just might be the one. I use dual 30 ga 7 wrap at 1/16th diameter and it comes in at .7 ohms and this thing just blows hard. Almost as good as a rda....
