Let's not forget about wood, either. My team has never used it, but take Rage Team 173 for example, they had their little red box (with an awesome ball manipulator) go all the way to the Championship finals (or maybe they won it). All I can say is that you shouldn't necessarily weigh that option out either. We all know it's easy to machine, and it can be pretty light, compared to steel. Aluminum is probably lighter, but I am pretty sure Wood is cheap. I just think carbon fiber and titanium are out of alot of team's budgets... It was on my team.
