Changing the resistor on the drive FET to something smaller would most likely improve the switch-on time, though since we've changed the design currently to running direct off the buffers, that seems a moot point.
Would be interesting to see how this changes with the new circuit we've got using the 74HCT/ACT series buffers. If it turns out the performance is very poor, then perhaps we could investigate the TC4426A/TC4427A chips mentioned earlier in the thread.
