Nice design! It is apparent that you took practical considerations into account as the primary design factor. There was a recent thread on CD, in contrast, discussing a mecanum wheel that the designer took aesthetic considerations into account as the primary factor... but as a result the wheel needed to be made on a 5 axis CNC mill in his opinion.

I can guess which one is more likely to show up on a robot!

As for the bumpy factor in the ride, you could always (at this cost) build 8 wheels, and attach them in tandem, with one rotated 30 degrees from it's partner... much the same way you can use two omnis to smooth out the ride.
