Actually i cant suggest that you get the p18 fks, I've had the Zrace bidnings, which have the same heel piece--if im wrong disregard this comment. But anyways the two bars that hold the heal piece breaks pretty easly, if you ski hard. Also there are some crucial pieces that are made of plastic which can break easly. I've broken mine 3 times, luckily the first two times my friend welded back on, the third i wasnt so lucky and a crucial plastic piece broke.
Im sure there awsome for racing but i mean they werent built for freestyle, why do you think they only sell them to racers, because there built for racing. Go get some p12's or jibs.
