One thing I haven't seen however is the potential use of solenoid actuators for shifting and that might be something to look in to as a pneumatic alternative.

Interesting thoughts. My team has all the pneumatic parts needed for a whole system but didn't see the need because we would have only needed it to push a disk into our shooter wheels. We opted out of that and used a vex motor instead. It works much better in my opinion and is far simpler. We also thought about it and we really didn't need to do a pneumatic system to do well in this years game despite the many things we could have used it for. Even thought the weight is not an issue it's the fact that we have to add a whole system to our bot to do things we can do without it. Are all solenoids legal? That might be something I will have to look into doing to shift since I don't see my team using pneumatics anytime soon even with it's possible gain. Unless they make sense in next years game.
