Somehow, I'd guess that there are as many ways to connect the toriod, as
there are
to make them.
However: My personal experience shows that placing the toroid slightly above
the top
turns seems to work best.
On my 3.5" coil, the toroid shades the top 3-5 turns, on my 6", the toriod
plane is about 1/4" above the top turn. In both cases, I get no corona from
the coil at all, just breakout from the toriod (and massive corona from my
strike rail)
