We used 6wd long orientation, with 8" pneumatics from AM, and the Super Shifter. In hindsight, The pneumatic wheels had nice traction, but were a pain because their sizes varied quite a bit. I would have preferred colsons from what I have heard of them. We had originally planned to go over the bump, but ended up not being able to due to geometry, I wish we had gone with smaller and more wheels to enable this. Also, our Supershifters had the wrong ratio for 8" wheels, so the high speed was too fast for our drivers and was thus never used, leaving us with wasted weight and a tad slow. I would have switched the gear ratios to slow everything down a couple fps or switched to a lighter and slightly faster 1-speed transmission.

Did they have an additional mechanism to aid going over the bump? I know 111 tipped up the front of their robot to do this, but I never saw exactly how this was done.
