I'm very jealous and curious of your 7 victor controlers on your electronics board. 4 are probably for the CIM motors on your drivetrain but what are the other three used for other than controling the arm?

Aluminum will definitely be more sturdy. We chose PVC so that if our arm would become tangled with another bot or element during the match the pipe would bend instead of break. And Theotherguy is right, we have a 6 motor drive train, the seventh is for the arm. We have two spares just in case we need them.
