Your binding is the basic Axial2 heel. If you got either the FKS series or the FreeSki2 (120, 140, 150), they would come with the World Cup heel design that is much beefier. They could still tear out of your ski like any binding could, but the heel trays wouldn't fail like that.
If the shop has older look/rossi jigs then they will be able to mount FKS bindings. Our shop got a new Rossi/Look jig in last season and it didnt have the heelpiece hole pattern for FKS bindings anymore.
