Alright so heres the deal. 4frnt stopped buying the vist binding because when you got beyond the 12 din binding, the whole binding was the same just with a different spring in there for higher din settings. Because of this, the higher din bindings had a tendency to break becuase the rest of the pieces in the binding werent able to hand the stress. They switched to a tyrollia binding this year so now the higher din bindings acutally have better contruction rather than just a stiffer din spring.
As far as mounting and screw patterns... i am not positive... but im fairly certian that the vist and tyrollia bindings do not have the same exact pattern. Same goes for the tyrollia and salomon.
