Looking at all these mouth watering blower pow pictures which are posted here and on other boards (Rockies related), I recognised that most of the bindings on touring skis seem to be mounted slightly forward, other than the average European mounting position, which seems fairly in the back. Also Canadian/US skiers seem to ride longer skis than the average European guy does. So maybe it seems to have the bindings more forward but it's just the longer skis, which make other proportions on the pics.
A plus for forward mounting would be, that you don't sink to much, because one is in a more centralised position. A con could be that the ski is overturning to much, like oversteering in a car.
My 175cm planks with Fritschis are pretty much balanced. When I lift one ski neither tip nor tail move up or down. The middle of my boot coincides with the marking on the ski, which presumably stands for the ideal position.
What's the benefit of having the binding mounted forward? Is it for turning ease? Or is it all just in the contortion of the pictures?
