Steve, all,

Nice work, does your concept work basically like Larry Robertson's 
H-drive circuit?  I can't quite picture your circuit.

Does the bang size stay the same over the bps range?  Or does
the cap voltage sag at a higher bps?  Is the spark growth linear
over the bps range, or are there ranges of faster growth, etc.?
A graph would be nice if it's nonlinear, and if the voltage doesn't
sag at high bps.

Thanks,
