Oh, and a quick coil resistance question to get us posting here--
I've been using the same coil for a month or so, just re-wicking it as needed, and the resistance has been slowly creeping up. It was 0.51 ohms when it was brand new, and is currently at 0.54. Is this just gunk collecting on the coil, slowing the current? I've been burning the crap off the coil in between wicks, but this still seems possible.
But anyway, is this rising resistence a suggestion that it's time to replace the coil entirely? Is it a sign of decay or something? Does this even make any sense? I'm kinda new to this stuff, so haven't seen this before.
