SSTC- feedback vs. none

My "bucket-primary" SSTC sits there un-fixed but I hope to get to it 
again before I expire.  In the interim it's occurred to me to ask, 
Why bother to employ feedback to sustain oscillation, when circuit 
phase-shift and/or inability to track exactly the secondary's Fr 
requires that excitation cease after the first few cycles, to evade 
that pesky "notch"?  Absent contrary words from the wise, I'm 
inclined to change my setup to a) stop each spark event after a max. 
of just a few cycles and b) merely use the starting-oscillator I've 
already incorporated to provide the drive to the IGBTs.  I currently 
employ a binary counter to cut off the drive, which would yield 
cutoff at only 2, 4, 8, etc. cycles.  If I change that to a 
decimal-output counter, I can cut off at 1, 2, 3,...10 (or maybe 9) 
excitation cycles.

What say you?
