My friend from BC, an alumnus of Trobotics (is Jason here?
) was talking about how the Cascade Regional webcast is far louder than the Olympic Regional webcast. In the pits, Cascade music definitely drowns out Olympic music.
About the tubes--
For our practices matches, we've had to make judgment calls during the queue for Olympic because of the discrepancies in tube sizes. We have a strand of latex tubing across our gripper to more easily account for different sized tubes, and we change the tension based on how inflated the tubes are from the queuing line.
