I have contemplated rebuilding my evod and pt coils. I've watched a video or two on it. Doesn't seem TOO hard, but I agree that's a good place to startAnd yes my itaste reads ohms.
its easier to build an Igo or a kayfun then an evod and both work better
they are a great place to start
gennies are a pain and only some flavs work well with SS mesh
I am liking the kraken with cotton but would not suggest that to start
