Are you positive that the primaries are wired correct??  They are in series 
but the inner turn of each coil connect together, and the outer taps connect 
to the primary circuit.  This is assuming that all of the coils are the same 
direction wound.  Are you grounding the secondaries or just connecting them 
together?  This didnt make a difference with my twin coils, but it may with 
yours.  And maybe try discharge points of several inches long pointing at 
each other form each coil.  I have had the same problem as you (much smaller 
scale!) but with hours and hours of playing, they eventually got along.  
Then i got bored with them and made one large coil(hehe, liked the single 
long arc rather than 2 smaller ones).  Good luck, and very cool project!
