As a final test I used a 0.009 microF MMC made up of mica caps (2500 
VDC 0.01microF). These gave less spark length than the other types I 
tried (11" vs 16")."

   How many of those 0.01 ufd capacitors did you use in series 
parallel to get 0.009 ufd?  I'm surprised at your results as mica 
capacitors have always worked very well here and were the norm in 
high-power spark transmitters.  I use barium titanate capacitors as a 
rule, because of their small size and low ESR, but they're lossy and 
can't stant more than perhaps 30 second runs without puncture.  Spark 
length seems as good as mica.
