I know this is still in the wrong place, but the saga continues. I went ahead with the twisted 28 ga. build. I decided to go six wraps on a 1/8" bit to avoid having my coils too tall to manage. I had never built with twisted 28 at this ID, and WOW it did not want to cooperate. After a long and epic battle, I triumphed, and these huge wicks pack some FLAVOR. I admit the coils weren't as neat as I like them, but I hit my target of 0.5 Ohms, so not too bad for the first try.
