Hi Luke
The larger toroid above tends to aim the sparks upward and helps prevent
arcs to the primary. To see with and with out the smaller toroid see:
http://members.iinet-dot-net.au/~pterren/tesla_coil_sparks.htm#6%20inch%20coil%20(the%20best%20ones)
(all one address)
The toroid E field tends to direct them up. My 6 inch coil (on the same
page) puts out a max spark of 96 inches from a 32 inch winding (i.e. a 3
times ratio) and never strikes to the primary with 2 toroids.
Cheers

ps "bare with me" sounds indecent.
