This is why I stated that in my original email that both driver circuits
would be synchronized.  In fact, I would even be using adjustable delay
lines on each board to account for all
propogation delays inherent in the connections between boards (for sync
pulses that is) so that the outputs can be matched to +/- 50ns or better.
