Not a bad tactic. I think the current rules give the lead buggy the right of way. So if you know you won't win the free roll, you can put King Kongs on hills 1 & 2 and then just block them from passing during the roll, thus nullifying some decent team from moving on. I think we may have done this once or twice to Spirit B with our Pika C, only we beat them on the roll and pinched them near hill 3.
And my question...
What buggy is cutoff in the back right of the image? The half-sphere/bubble front on derbies. Do we have any other pictures of that?
