bootsole, weight, and height doesn't mean shit when your not a pussy...if u ski hard your shit is up I guarantee it. anyone who skies like a pussy doesn't need thier dins up past 10 on any binding. but once u start sackin up, specially off cliffs, u have to crank the din UP...
I ride race stocks and they are up to 13, but still come off when they shouldn't sometimes, they are older bindings though
