I have Fritschi's on 4 of my 5 pairs of BC skis, one pair I have Dynafits. My freerides function just fine, I have 3 pairs that have been skied hard for 4 years and function like they did day 1. solid binding. I Resort and Backcountry with them 2-3 days a week during the long Alaska winter. I see reviews and things out there sayin Dynafit this, lightweight that, but releastically there are unfit BC skiers with Dynafits I lap, just get in shape and who cares. I have found (and there are blog entries that you can find about it) certain model BC boots and Dynafits not playing well, I will say I stopped skiing my Dynafits because I use top of the line boots (brand accomodating a wide foot) and my Dynafits and my BC boots do not play together well. There are many solutions in the blogosphere about grinding certain areas of the dynafits for extra clearances here and there on teh binding, no way! As now with the Dynafits I have to ski down in locked touring mode (approx DIN 19) or the toe releases. That just leaves me at risking knee damage otherwise, when I turn my outside ski releases, do that twice on a steep face or gulley and see how many more times you ski with those. My freerides, NEVER have done that! They are the unsung hero of BC skiing, so get in shape and throw a couple extra pounds on and ski with confidence, knowing your binding is ROCK SOLID!!!
