I feel like I'm missing an obvious design cue with this. My first thought was "they should've put the pneumatic wheels on the ends and the omni in the center so it could absorb the hits while still being able to turn (with the raising and lowering of the front and rear)", then I wondered if rotation would still be feasible with the friction.
Still, very innovative design. I like it!
Answering the question, we went with the standard-ish AndyMark Rhino module treads. We're definitely making our own drivetrain next year.

It turns great, never had a single problem. Turning easily was actually one of the reasons we went with this design.
Ex 1 Ex 2 Just a couple matches from Hampton Roads to showcase. (Our shooter was shut down due to bumper rules, or we would be doing more than breaching.
)
This thing was actually pretty quick, way quicker than the mecanum drive we had last year.
We never had a problem other than one of the axles on the pneumatic wheels bent in Blacksburg. (Weird, huh?) That was probably the worst that happened. We had the pressure set wrong in Hampton Roads, so we were really bouncy and had to take it slow, but since we had the pistons taking most of the shock, they never had any problems. We inspected them after every match to make sure they weren't cracked or broken.
I really enjoyed the challenge, and it won us the Innovation in Control Award in Hampton. I think custom frames and drivetrains will be in our team for years now.
