Kevin, all,

I wonder if the 
radically swinging inductances that may occur using inductive
ballasting alone, cause peaks and valleys in the firing voltage,
such that the gap misfires at times (due to a too low a voltage),
and requires closer total gap spacing to insure firing, thus, the
static series gaps can't be tolerated.  It would seem to be a
voltage related thing.  Another possibility is simply that the
pure inductive ballasting is creating such high peak outputs,
that the system needs to be spaced/insulated better to handle
the higher voltages.  Very interesting the way these factors
work together.  Yes, I'd like to hear of other's experiences and
views on this too.
