I'm about as close as you'll find to vaping exclusively 1-battery mech squonkers.
MOST of them sport a simple 26g. 316L SS coil in the range of 0.45. That's 5.5 or 6 wraps. Often spaced. Some 2.5 and some 3.0mm.
I have a few RDA's that need a dual, for which I fall back to 28g. Ni80 so I can land in the same resistance range.
I have a very small selection of purchased coils (claptons, fused claptons, and aliens) that I'll toss in the mix occasionally - literally have a few of each, and don't know the specs offhand except most recent purchase from Fresno Fog that's thoughtfully labelled "MechAlien, 28/36 N90 3mm .24 ea". Thought that might be "too hot" for me - but while a bit "lively," it's vaping just great.
