I started with my T3S, and then the Mini PT 2's... it did improve the vape a little, but i still had a very hard time with wicking, in those small heads. Once i got my first kayfun, I was able to make much fatter coils (7/64) and that helped, plus getting some organic cotton (cotton balls, from walgreens). As big an improvement as the vv3/T3S was over the eRoll, it was that much better again when I finally got a kayfun vaping well, just night and day difference -- I had to moderate the high TH for a while until I got used to it, it was so much better.
Now I pretty much just use 3/32 for my coils, usually about 6 wraps, and I'm pretty good at the wicking part now. I may be a serious tootle puffer, thanks to my asthma, but I still want a great vape, with strong flavor and fairly intense TH; I only need as much vapor as approximates what exhaling a puff of cigarette smoke was like, and that's not really that much -- when I was tapering off, I observed it quite closely, to know about how to figure my "sweet spot" with my vape.
And yes I know the talk of coil building is tedious to some; just pass over. It's actually a sort of art form, to make a good, well-performing coil that won't crucify your lungs, to make that tootle puff *just right*!
