Of you want to vape at high watts then use kanthal. I vape dual parallel 24awg kanthal, 4.0 or 3.5 I'd, 6 or 7 wraps...i vape that at 130 watts constantly, I can and do go up at times. Resistance is around .12 to .18 depending on wraps or diameter, although I have got dual parallel 24awg ni80 on right now, 9 wraps, 4.0 Id, 9 wraps, resistance is quite high at 0.4. Smoking it at 100w, I use a rx200 btw. Yes my builds throw masses of cloud,great flavour. I wick with cotton bacon...
