Don, Reinhard, all,

With the 6 sided standoff, the sparking is spread over a larger
area if you use the flat sides (than would occur with a round pipe),
and produces less "spot" heating.  Was the 6 sided standoff
compared with a copper 6 sided standoff or other flat type gap.  In
general, I think I've seen better performance with flat gaps than with
round gaps.  I've had good results with silver faced flat static gaps.
