Malcolm, All,

Thanks,  I see exactly what you're saying now...  Have you compared
the quenching ability of twin coil with that of a regular coil?  I suspect
(based on Robert Steven's results) that a twin coil may give a more
optimal loading.  Maybe even a triple or quadruple coil would be better
as far as optimal loading, but probably not for spark length.

Comments?
