I strongly suggest everyone who thinks that 8020 is an terrible material read this:

As I have said before, 341's 2012 robot is one of the best, if not the best, Rebound Rumble robots. They finished the season seeding first at EVERY SINGLE EVENT they went to(including IRI and CMP), 87-9-1, division finalists, and IRI finalists. They maximized their resources, using what little resources they had only where they needed it. I love using box tubing because we have the machining resources necessary to fabricate with it and it permits us to build extremely light robots, but 8020 can be just as good if you need to build quickly with little resources.
