The weakest link??

Hi all,
I just got back from round two with my first coil. As you recall I had
pretty good arcs from my first attempt and then started to see the side
breakout from the secondary. This was reportedly from a toroid that is
too small or too high up. I went back today armed with a new 4 inch dia.
toroid that is about 16 across (the old one was 3X14).
We tried tuning that sucker for I bet an hour with no discharge at all.
I put the old one back up and chopped about 3 spare inches of coil form
below the toroid and got good but not great results. I tried both
toroids-nothing, then just the big one, lower down as well and found one
spot about one turn out from normal it would make one arc every 10
seconds or so. I cannot duplicate the pretty good arcing I got after my
first attempt(last week) with any toroid or tap combo apparently
although the original sweet spot (and the original toroid but lower)
still arcs away just not like before it seems. 
Questions:
Did I cook something? One leg of the NST, or the cap perhaps? Is my main
gap just getting corroded (it looks pretty good)? Was the second toroid
just too big for a 9/30? My Dad said more voltage required and the whole
thing sounds wimpier.
It pretty much stunk overall, any advice more than welcome...
