We haven't tried to climb onto platforms, but 3946 has experience with mecanums that were WAY out of balance. Our competition robot last year wasn't too bad, but our proto'bot, made mostly of 2"x4"s, only put about 10# of force on the left front wheel (total weight in excess of 100#). Our drivers learned to compensate well enough that a casual observer at practice would not have suspected how out-of-balance we were. I demo'd "Woodie" at my office with absolutely zero drive practice, and impressed my co-workers (mostly scientists and engineers) with the capabilities of mecanum - I could execute all sorts of translation as well as rotation.
