Skip,

The only reason longer sparks are afforded by larger diameter coils is 
that they have much more inductance!  with the jump from 4" diameter to 
10" diameter, the inductance jump per foot of winding really leaps into 
the stratosphere!  Again, it is inductance in the resonator that drives 
spark length.  To make it happen effeciently, a lot of thoughtful and 
knowledgable shepherding of system components is needed.  This includes 
proper loading, power balancing, and gap construction. (the art of 
coiling)
