Gabriel,
I dont know whats up with the ball number that FIRST provided but the are different!
The balls we got seem to bounce the same. But the reason I don't like the difference in the stickiness is because we want to see how the balls move on the floor when pushed by the robot. In 2000 many teams rode up on the balls and we wanted to test different wing designs
(the balls bind when being pushed...)
I will try to post a picture tonight on the difference of balls
Bad Brad
