steel if you have the weight, titanium if you have the supply...same for carbon fiber...but isn't daydreaming nice?

Anyway...more realistically...bosch (spelling is probably wrong) Al would be close to the weight and the internal structure on it might help it hold up a little better...

How much weight do you have to work with?

But really honestly if it got "stuck" someplace you would probably be better off fixing it so it doesn't get stuck than getting a new material. A flaw like that could show up no matter what material you use...plus issues like weight and center of gravity...or even if it does hold and you still get jammed mid-match you could become useless.
