Joie, my first step in rebuilding was just replacing the wicking with cotton in the ProTank 2 single coil. I had no intention of making new
coils, but everyone was talking how great cotton was. I had to try at least the rewicking with cotton balls. Ha! That was 18 mos. ago and I've gone on to using cellu cotton (rayon) from Sally's Beauty Supply and 30 guage Kanthal for my PT's rebuilding anywhere from 1.5 to 2 ohms.
Taxguydave ain't lying when he says you can use the ProTank 2
coils. Took his info and tried them my ownself in my Subtank
mini. Worked like a charm. Can't thank him enough for sharing this other option.
