I started out with 12kv neon sign transformers and now use a 14,400v pole
pig.  I have my safety gaps set at 1/2" on each gap.  They never fire unless
I get a strike directly down into the primary.  I would guess that you are
not running in tune and kickbacks from the primary are causing the gaps to
