With the spark gap being only a few mils for firing at a few hundred
volts, it sounds a bit futile to hope for any long term consistency in
gap firing voltage.  How about taking a lesson from the auto makers and
using these coils like they were designed?  Use mechanical points, a.k.a
relays.  We don't actually need a spark gap, just a timed closure.  Or
better yet, anyone know what cars use nowadays as far as solid-state
points?  Now there's a triggered gap!
