hey i found some cheap px12 racing bindings on evo. i know this means that there is more metal in the heel, but what about the toe? it just says full drive toe so i don't know. anyone have any idea? also, anyone have any idea how the weight compares with, say, fks 140/pivot 14? I am about 5'9", 135 lbs. all info is appreciated and will be rewarded with...-drumroll please-...+K! and my respect.
