Hey Chris...

I was looking at the pictures you had posted and noticed your spark gap 
...   it looks as if you have ( in the picture anyway) the gap setting way 
too tight. Open the gap setting to about 3/8"  for 11KV. the tighter the 
setting ( smaller) the less voltage is required to jump the gap resulting 
in shorter streamers. Be advised tho...  this gap spacing trick isnt the 
means to get longer streamers beyond what your system is designed for. 
There is a limit as to how far a gap can be opened before it will either A. 
blow your caps, B. not work due to the gap being too far apart.
