I have to agree. There is no "best wheel", but there are better wheels than those in the kit of parts. It all depends on what you are trying to achieve. If you want you robot to be very maneuverable, using a combination of omni-wheels will help. For traction, the IFI traction wheels are good. We have had success with Skyway Bead-Lok wheels by custom cutting them. Another factor is the setup of your chassis. 4 wheel or six wheel - middle wheel lowered or kept at the same height. These are all decisions you need to make depending on what your objective is. If you are at the championship, I would suggest you check out different drive bases teams have built. By talking to them, you can learn a whole lot of principles and concepts they used. Additionally, check out all the pictures and threads about robots on CD. There are also many white papers written on building a successful drive base. Good luck.
