Hey Rick, Have you ever tried doing unloading snaps. You only tap the elevator to begin the snap, then release the rudder a moment before releasing the aileron. Very precise and clean even in 3d throws. My Edge will go way to deep into the snap if I just bury the sticks into the corners. (this is in high rates. My low rate uses very little rudder and elevator so unloading the snap is'nt nescessary)

I hope this helps but I would want to hear what the BAM man says his technique is.
