Luc, all,

In one test, I compared a 4" x 23" coil with a 6" x 24" coil, both
wound with 28awg wire.  Both coils performed very similarly.
I began to get coil breakdown when the sparks reached around
61" or so.  The 6" coil seemed to tolerate slightly more power,
but that's probably because it was an inch taller.

In another test, I rewound the 6" x 24" coil with 660 turns of
20awg wire.  This reduced the spark length by about 10% to
38" from 42" before.  I didn't try higher powers.  

These tests were all done at 120 bps.

Cheers,
John
