I also see small gains in acceleration and top speed in my model for conservatively geared robots. Some reasons I'd still consider 6 cims over 4 on a single speed bot geared at 12 ft/sec:

1. 6 cim is more efficient than 4 cim during high loads like pushing and turning (less motor heating, less speed drop under load, robot seems a little stronger)
2. Distribute load between motors to reduce heating for back to back matches
3. Redundancy, we lost a talon last year, robot was still very much driveable other than not driving straight
