I'm using a dual coil 8/9 wrap at a 3 mm. Ohms out to .16 with 24 guage at 88 watts with temp really decent clouds compared with kanthal without temp control
What I did was fire at 10 watts for a few seconds and then unscrew the Atty then screwed it back in and let it run at different ohm
I'm using ti wire the original ohm is at .16 I have it at .19 to be able to use temp control and get decent clouds
