Last year Team 967 used 8" mecanums directly driven with regular 12.75:1 toughboxes. We're going to do something similar again (we see no reason not to use Nanos this year), because it was nice to save some weight (no chains) and some time (no chains). It was a pretty fast drive. At its full competition weight, it needed a bit of a running start to get up the 45 degree ramps last year, so we would have geared it down a little bit for last year's game if we had it to do over again. But this year has a flat field, so we are going with the same thing.

You would not want to directly drive 8" mecanums with 4.67:1 Cimple boxes. It would be interesting to see how much you can push the speed beyond the standard 12.75 ratio, though.
