Familiarity: I've put it through the wringer
As far as holding your boot securely on the ski and safely releasing, these bindings are fine. But trying to get them on in deep powder or loose snow is a real problem. I used them while heli-skiing and found them extremely difficult to get into each time I got out of the heli into loose snow. It takes a lot of force on the heel to snap into them (and I weigh about 200 lbs) and the toe piece is really prone to getting clogged with snow. I was very disappointed. Everyone else on the trip had very few problems getting their skis on - while I required assistance several times. Not recommended. I am going to switch them out for Salomon bindings next year.
