Well gosh darn, if I would just read the instruction manuals more often I might learn sumpin'. That explains why I usually get a better vape in the high 4V range than I do at the low 5V range when working w/ coils between 1.6-1.8 ohms on the Provari.
ps: vapdivrr, I've yet to work with 28g or ribbon kanthal 'though I have some of both. Before ceramic came around I was trying different mesh, and different styles of wick (thin, fat, straw), the ceramic came along and it was Fishsticks, round FC's, slotted FC's, white ceramic. I stuck with the 30g on all my builds just to keep something consistent. That and my primary PV's are a few Provari's and a couple backup Zmax's. But in the next couple-few weeks I should be getting my 1st mech mods, then let the 28g learning curve begin.
