The other thing I found is that the latency with FireWire interfaces is pretty much the same with all of them. Sorry to be argumentative, but I have to repeat that I was expecting to find a difference but didn't. That's on Mac. On Windows there is a definite difference between drivers, in fact the CEntrance FW driver made quite a difference.
