for one you cannot really use 32g wire on a low resistant set-up
Just on that I disagree. I use 32g for my phoenixs and keep doing 1.2 or 1.3 ohm (sure, not 1.0ohm or below, but still low) consistently. I really like how fast and hard those hit.
Those I use on cheap EGOs and they work very nice, one of my favorite setups.
I couldn't do the same with 28g on a phoenix, everything is too close and I'd need one too many wraps.
Anyhow, the 28g coil i did today is starting to break down and giving better flavor. I may become a fan
