Congradulations!

I use 8 AWG stranded, PVC insutation. It's designed for car audio
applications and is VERY flexable and easy to work with. The correct ring
terminals are crimped on the ends for quick and easy connections. I don't
use more insulation, I just keep the runs away from everything else, it
seems to work fine. The only exception is the connection to the primary, I
use hose clamps for that, and just clamp the stripped wire to the copper
tubing primary.

I just run it up there and tape it down with aluminum tape (any hardware
store has it).
The problem you are having with corona could be that your topload is not
big enough to prevent breakout, so your wire has extra power available.
Try a aluminum dryer duct bent in a circle (more tape to hold it) to make
a toriod. Start small and work your way up. I'm using a 4" diamater tube
with about 14" diamater center-to-center spacing on the toriod on my 6"
coil.. I think I need a bigger one.
