On a old pair of Fishcer Hybrid 8.0's that I bought at a ski swap for $100, and they have Fischer demo bindings with the standard demo track (335-350 and abcde... etc.). I have been pre-releasing alot recently. I am 6' tall and 136lb without gear. When I land switch after small jumps, I pop out alot causing me to crash. When going faster through rougher terrain after a jump, a ski pops out and causes me to crash. I noticed that they pre-release almost exlusively after jumps, primarily switch. The only thing I have changed on the bindings from the ski shop settings was the DIN to 7 (from 6) in attemt to reconcile this. With my Axial2 120's that I have on my Powder skis, I set them to 6 and have had no problems. I think it may be a foward pressure issue but I cant seem to find the marker that tells me whether its fine or not.
So whats wrong with them? Is my forward pressure off? Is it just a crappy demo binding (No other demo binding i've used had this problem)? Are my bindings broken?
