I hit mine w/a 1/16" drill as soon as I got it. That size always seems to work for me, but I haven't ventured into dual coils.
if you want a super vape on the cyclone, do a dual coil on a single wrap. If you do about 12 wraps of 30g kanthal on a 3/16 drill bit, then wrap a second coil between the coils of the first, you'll have a single-dual coil that is incredible.
