Familiarity: I've put it through the wringer
I put these on a pair of Scott Punishers a few years ago, and they are not making it through. I have bindings on skis that are 10-15 years old that are still doing the trick. However, this is another story. I'm 6 ft 2 in and just over 200 lbs, and these didn't handle the job. I've had plastic break on both bindings (right under the toe piece). Bindings still work, but it's going to go soon.
On the east coast, my back/sidecountry days are limited, and these mostly saw time inbounds. I just mounted Look bindings (http://www.backcountry.com/look-pivot-14-ski-binding) on Volkl Katanas, and am very pleased. They are heavy, but worth it. I'll keep the Barons going for strictly backcountry days.
