I have 2 different styles of Nichrome that pretty much sit since I found Kanthal A1 and I have 32g, 34g, & 36g... I typically use the thinner 36g for HV coils between 2.5 & 3ohms... and use the 32g for dual coil set ups 0.9ohm @ 3.7v... and as of today I just got the 34g and will be playing with...
