Just did my very first Protank coil rebuild and it went surprisingly well. Used 30ga Vaporwire and cotton wick (yarn). Got 1.3Ohms. Vapes like a champ with pretty decent flavor. I wasn't super careful with my coil wraps and didn't torch it and all that. Did have an issue with it grounding out. Looked it over and discovered one of the wires didn't break off inside the rubber grommet and there was a TINY bit of exposed wire. Next time I'll take more time. This go around was just feeling it out. Quite surprised how easy it was.
