This year, 1293 is going with 8" Skyways on the outer four wheels, and IFI wheels in the middle of our 6WD setup. A big reason for this is cost and lack of need--six roughtopped wheels from IFI, doubled for a practice robot, would be quite expensive. Since we seem to be driving around just fine with our current arrangement, with no noticeable wheelspin even on our slick tile floor, we're sticking with it.

On a side note, these are actually the lightest wheels we've ever used on a robot. On Bob, we used the 12.5" pneumatic Skyways that came in the kit. Last year, we had these big heavy 8"x2" wheels that, ignoring cockroaches, would be the only things to survive a nuclear blast. Staying with lighter wheels this year is a change for us, but I think it's definitely working for the better.
