Trust me dont get racer bindings on your skis just cus pros have'em, they rock them cuz they get free skis and binds.
Yes there increadibly light, but the heal piece is weak, i've broken mine three times this season. If you look on the FKS's there are two rods that hold the heal piece, well those tend to break, same with the small plastic pieces in the heal peice, that like to break too, rendering your bindings useless.
Remember race bindings were built specifically for RACERS, why would you put them on your park skis. Instead of putting extra $ to get race bindings stick with there regular stuff like jibs p12s, etc.
