I'm pretty sure no one should ever listen to you. Ever.
912s are shit, Z12s are shit, they are almost all plastic and will break piece by piece if you ski hard at all.
The issue of ripping bindings out is because you ski hard, most certified shops you take them to will mount them properly.
If you're going to get Salomon, get the 914 or better, or wait for the STH 12 to come out next year. It's based on the Z-series binding, but way beefier and better built.
