Have you thought about twisting your 28 guage. I use the end of a pen and a pair of pliers. ;-)
6 wraps around a 3mm bit. 0.3 ohms and dense clouds.
I haven't yet, but I'm considering anything, ill have a play with whatever is recommend, and just keep a basic build in for now till i get something good in. When you say use the end of a pen and pliers, can you elaborate a little. For some reason i can't picture twisting with that? Don't know if its because its getting late and i can't think properly, along with a few beers.
