Yes, I dont think the SSTC arcs can compare to mine.  When i was running my 
VTTC, i was really in awe.  The sparks formed a perfectly straight channel 
and each spark was in the same place (maybe .25" difference!).  It was just 
like one streamer in stand still!  So, i get up and walk up to the thing 
and just started gazing at this plasma right before my eyes (literally 
about 10" from my nose!).  For some reason it just captivated me!  It was a 
very surreal moment.  Think about it, there is this thick popping tendril 
just sitting a few inches from you face, and it wont do anything to 
you!  The sparks were so straight, they would not change their path to even 
give me a nice zap to the head!  It was really incredible how tame yet 
powerful the sparks are.  I wish everyone could experience what i did.  Im 
sorry, but my current SSTC does not compare!
