never used a kayfun i just got my first mech and 2 rda's not even 2 weeks ago lol.
i used 24 gage kanthal and it rips lol, i got a dual coil set up on my stillare at 0.27 ohms and my little cyclone can hit almost as fat with that stove top, oh and i used sterile cotton clouds a small one behind and another small one under it.
