we used a "wide" chassis configuration. at first we used 4 KOP high grip wheels, all driven. we COULD NOT turn on carpet with this set-up, even with the wide configuration.

we ended up using slippery white wheels in front, not driven, and two high grip wheels in back. we were able to maneuver very easily and pick up balls really quickly. since we could shoot reliably we scored a lot of points.

we were able to go up the bridge, but if we tipped to the other side we were not able to back up. we were able to balance, but had to be very gentle.

so overall the low traction setup worked well for us, but not so well on the bridge.
