You might want to also consider a gas shock of some type. McMaster Carr sells them in several lengths and forces.
We used one on our arm to provide some assist to the lift motors and to dampen the movement.

That's awesome that flow control fittings are legal parts. But I can't seem to find that in the rules. <R65> says that "no pneumatic parts other than those explicitly permitted by the Pneumatic System Rules may be used on the ROBOT." <R66> lists the pneumatic parts that are specifically allowed on the robot, and flow control fittings don't seem to be on the list. However, "kwotremb," who also responded on this thread, says that his team has used flow control fittings on their robot and it has passed inspection at 3 events, so it sounds like it's not a problem. But I'm still puzzled why flow control fittings don't seem to be explicitly allowed in the rules. I may be overthinking this.
