With a 6 inch dia. secondary either a 12 x 3 or 14 x 4 inch toroid will
give good results.  The idea is to get a nice breakout so the sparks dance
around a lot -- more esoteric.  Larger toroids will give greater outputs
with a large xmfr to drive, but the breakout value tends to be high and not
as neat with the spark discharge pattern.  A 12 x 3 will produce very
exciting results with a 60-90 ma drive source.
