John, All!

John, I must agree with your "intuitive sense"! I does seem probable that 
the intense heat formed from CW VTTC (even pulsed) will provide a intense 
(hot!) ion path for sparks to follow. Thus reducing the potential growth 
per cycle...

Perhaps a "Super Staccato" VTTC could produce similar results as a Spark 
gap coil (at least research wise) with less burnt Silicon, ;-)
