Glad to see people are interested in this, I did play around with pure wheels for a while, but got nowhere fast, but I think motorbikes are proving surprisingly versatile, we've not had to resort to ones that go left, unpowered bicycles, or contra-rotating ones yet, and there are always plain wheels that could be used to pad out areas of the course too.
That big ball solution is very impressive, possibly even faster than throwing the ball!
