Gerry,

My 6" coil has two toroids.  If I run at full power with only one, I get 
lots of sparks going down toward the primary.  I am presently using a 30 to 
33" toroid on top of the coil and a 40" toroid raised up above that.  The 
majority of the sparks leave from the upper toroid thus giving me more 
clearance to the primary.
