There is a good chance that a Rogowski shaped electrode would help.

Our very own Jim Lux once posted a very good spreadsheet that covered 
the design and characteristics of the electrode shape.  I believe 
using his spreadsheet, and a bit of careful grinding, one could 
approximate a good curve and then compare spark characteristics?

How about it Jim?  Still have the rusty (I mean trusty) old sheet handy?
