Go to Post But should we "discriminate" based on how long your team has been around? If you think about it, FIRST's goal is to inspire students, right? ...But students on rookie and second-year teams, if anything, are in greater need of being inspired. - LauraN [more]

Ah, now I get that rule. When we were doing our tests this week we were able to get the speed we were looking for out of 3x 1/8 tubes, so that is why we laid it out with three. We thought ithat rule meant that we had to have a valve on each input to the cylinder. Thanks for that piece of feedback.
