I wouldn't use a rotary gap with NSTs; you'll burn 'em up. Just add a 
few more series
gaps, perhaps even a muffin fan, if you run into quenching problems. I 
used the famed
RQ style series static up to about 8 kva. Save your power for the four 
or five additional NSTs
you're going to wire in paralell with the one you have  :o).
