For more iterations and better practice, put that 12" wall up at the edges of your lanes. We found that it's somewhat difficult to see the tubes on the floor if you're in the lane diagonal from your driver's station. It will also get your drivers used to exiting the lanes where they're supposed to. For bonus practice, get your 2010 robot out to play some blocking defense.

Nice & Simple -- I like it.
