What Charlie said. Your choice of bindings doesn't have anything to do with it, it's a case of core integrity and/or adhesive strength if the whole topsheet pulls off like that.
respectfully disagree here. Yes if the ski had a burlier core and or beefier glass layup it obviously would hold up better in all situations but to say that a dynafit toe puts the same or less stress on each of its primary mounting screws as say a salomon, look, or a marker toe is far from accurate. Many if not most of the dyna pull outs i've seen either first hand or pictures of tend to be of this variety where the downward force on on one pin(side) causes the opposite side to pull out. since most alpine binders have an afd that sits flat onto the ski you dont create the same level of force on the screws as you can with dynafits, where the stress load is suspended above the ski.
