Hi Steve,

IMHO,it is not the toroid background E-field which is
of prime importance to support longer spark growth,but
the larger toroid ability to feed long sparks with
more CHARGE.
Even though for the same bang size ,inital terminal
potential may be higher for a smaller toroid used,a
charge surplus of a bigger toroid appears to be more
important (up to a certain limit ,of course)

Also,note that secondary with a larger toroid on
,exhibits  smaller detuning effects in TC system for
the spark of the same lenght attached.

regards,
Boris
