Robin,
That's the question. I've seen evidence in my work using potential
transformers and sync rotary gaps on a small coil, which suggests
that large cap, low bps, will give longer sparks for a given power input.
The low bps sparks will have a slow wavering floating appearance
compared to the higher bps sparks. If you try to run low bps non-sync,
you have to be careful to avoid certain gap speeds which will cause
in and out phasing with the mains frequency, and cause surging of
the output. Low bps will require a larger toroid to reduce the number
of individual streamers, if you want to reduce the number.

It's probably best to avoid resonance for your system.
