30 and 32G parallel coils were my exclusive go-to for a very long time.
Advantages of thin wire compared to thick:
-Reduced mass at equal surface area which results in...
-Faster heating/cool down
-Cooler vape, as its more efficient. Heats more liquid instead of air, less power loss at the legs, more vapor production at the same power.
-Broader power range. The coils start producing vapor at lower power and still can be cranked up if they are big enough.
I build DTL atties with this also. 80 Watts on a dual 32G build; no problem. You just need an atty with a big build deck, at least 3,5mm diamater (better 4mm) and LOTS of wraps.
For a more mtl style, I think thinner wire is pretty much a no brainer. Of course it´ll work better.
