I am in college (Does that make me smarter?)  I like Tesla map 5 as it is 
simple to use and understand, but it cannot tell you when you are using 
components that are out of spark range (AKA your top load is too big to 
permit breakout with your power supply).  With that said, we will need to 
know more about your secondary/top load setup, if you are getting that many 
streamers simultaneously, your top load is too small!  if increasing it's 
size doesn't give you the results you would like, your secondary inductance 
is probably too low (it must be a small secondary to resonate at 600 kHz, 
and a small secondary will always give you smaller sparks than a bigger one 
of proper inductance).  Soon well hear form an engineer, and then a retiree. 
  Good luck.
