Right, so here's the deal... Last year I managed to rip the heel-piece of my binding out my ski, meaning I had to get them redrilled. The shop that redrilled them - despite me giving them the sole length - mounted them with the rear bindings pretty much all the way forward on the rail.
Now my boot moves about slightly within the toe of the bindings, and I can't crank them any further forward to put more pressure on the toe-piece. This isn't a massive problem in the sense that I'm not double ejecting whenever I take impact, but it's pretty disconcerting feeling your ski squirrelling about underneath you when you're setting up for a kicker.
Any advice would be much appreciated.
