I purchased Protector 13s for three sets of skis. I ski 50 days a year, mostly in Jackson Hole and ski fairly aggressive terrain. I've enjoyed skiing the binding and I’ve had no problems with standard pre-release issue. However, In the last two weeks I’ve had the front binding slip forward on the mounting track two seperate times. This happened on two different sets of skis so it was not a one off defect. The toe piece moved forward on the track while I was skiing, and my boot came right out of the binding. When I went to put the ski back on I could not since the toe was too far forward, I had to adjust it to get down the mountain. This is really concerning me. One of these falls was at 40 mph and banged me up a bit. I want to see if anyone has had a similar experience? I skied the attack 13 demos for years which are on the same track and never had an issue. I’m thinking about using epoxy to lock the toe piece to the front rail, but once I do that I’ll never be able to get them off.
