David,

The main factor that determines how long the spark can be relative to 
the secondary coil, is the bang size, and indirectly.... the break-rate. 
If the break-rate is high, the bang size will be smaller for a given 
power input.  The bang size is the real key.  I use low break-rates
because of the better "efficiency" they provide, but this limits the
spark length that I can obtain from a certain secondary winding length,
due to the relatively large bang-size.  But it's a tradeoff that I'm happy
to make.

In the magnifiers, the resonator doesn't "see" the total voltage, so
the ratio can be higher.

Cheers,
John Freau
