I think for even 6" wheels, to use the clamp on gearboxes you really have to use the second reduction add-on to have good performance. Unless you're racing for the middle bins (and even then...) I would shoot for the 8-11 FPS range this year, but that's just me.

What do you define as a "very high speed" for mecanum? For me, high speed WCD is 18fps+ on 6 cims. For 4 cims, 17fps. Is mecanum actually that limited in terms of speed? I thought I read that they could go at least 15fps.
I don't think acceleration is a problem. A 15fps bot's time-to-distance is as good as or better than a 10fps bot for anything more than several inches. So you're not wasting current by running at a higher speed- it's very well used current.
EDIT: See here:
https://www.youtube.com/watch?v=YbluSr2Mf5Q That's a 15.4fps mecanum bot.
DOUBLEEDIT: I would test both speeds actually. I have never seen anybody even try a mecanum geared for more than that 15.4 one I linked above, so I would try 12:72 x 16:22 AND 11:72 x 16:22 AND 12:72 x 16:32. I would be very interested to see actual results from a team that has tried a fast mecanum.
