Would the hinge be bad for freeriding?
Is it mostly a freestyle type "feature"?
It's up to you, if you like lateral flex, then no it wouldn't be bad for freeriding. If you don't (a lot of free riders don't that's why you got hard booters and stuff), then it's probably not.
If you want a binding that's got a buncha carbon in/on it, but no hinge, try the Union Chargers.
