We'll definately be experimenting with using a different wheel types on one side during the off-season; I'm pushing for omni-wheels.

We used the 12" pneumatic wheels from the kit in the front and 8" pnuematics in the back. For the past few years we have used pnuematics and while they provide awesome traction, that is the tradeoff for poor maneuverability. At the beginning of this season we were going to have the same problem again until we went to Quincy. A few teams there had bought what I think is some sort of pool or plumbing tubing. Cutting those in half and tie-wrapping them around the back tires provided us with what you might call cheap and easy omni wheels. The ridges gripped for some decent traction going forward and back and let us slip to the side when turning. For any team who needs a quick fix I recommend going to Home Depot or another home supply store to pick some up. i don't have a picture handy but if I find one I'll put one up.
