Sorry, I hope this doesn't take the thread off-topic - I don't think it does, really.
I posted elsewhere about ski selection for when hiring skis. When I read a thread like this, though, it makes me wonder whether I'm looking at the wrong criteria. If binding position really makes that much difference, I may well end up hiring great skis but with the bindings in the wrong position for me. Unless I can change the position myself, which I know some binding systems allow but probably not the ones used on rental skis, would I perhaps be better trying to find skis by manufacturers whose factory setup works for me? For example, I've really got on well with all the Dynastar skis I've hired, which may be because they were great skis, but may it also be because their typical binding position (slightly further forward, from a posting earlier in this thread) works better for me?
Is it possible to compensate for a sub-optimal binding position by a change in the way you ski (your own body position), or are you inevitably going to struggle if the binding position isn't right?
