I've been using 28 ga nickel wire from Vapowire on Kanger subtank mini, Lemo drop, Russian 91%. 6-8 wraps on a #6 machine screw, usually come out to .13-.16 They all work fine. Some folks like to use a #8 screw for more wicking capacity but 6 works fine for me. KGD cotton....and a 12 pk of ice cold Corona with plenty of fresh lime wedges. I run the tanks on a VaporShark rDNA, 420-460 degrees, 20-25 watts, sometimes 480 degrees @30 watts if i'm feeling frisky or drunk or both, afc wide open, designated driver, I stick both feet out of the passenger side window of the car when cruising on a warm and sunny day (remember to apply sunscreen to your dogs so they won't hurt when you have to put your flip/flops back on).
