After doing a little reading about rebuilding coils, this sounds like something I want to try but don't understand a few things. First off here's what I have. Kanger tech mini pro tank 2 Itaste vv I've ran 2.0 ohm coils at 3.3-3.5 volts and seem to like the results, although I haven't adjusted it much. I'm wanting to rebuild with a 2.0 ohm coil and be able to run the same voltage I have been. I've also read that using cotton gives you more flavor and vapor? End results I'm looking for lots of flavor and vapor, not soo much with harsh throat hits. My juice is a 50/50 mix As for the wire goes, what gauge do I need go achieve 2.0 ohms? What's the difference between a micro and nano coil? And which one comes with my tank? Why do I need a torch to burn the wire with once wrapped on the needle? If there are any other basics I need to know before I try this, please let me know.
