The short story.
Last season I bought a pair of Sultan 94s and had them mounted up with Salomon Z12 bindings. Loved them. They lacked a bit on hard snow, so I picked up a pair of Sultan 85s to replace my Afterburners (which I kinda hated) for those hard snow days. Same length and bindings. Both from the Start Haus.
When I skied the 85s I felt like I was a bit more forward on the skis than with the 94s so I put them side by side, and lo and behold, the bindings were mounted on the 85s about 2cm more forward than on the 94s. Odd I thought. I also noted that the boot sole center line was 2cm forward on the 85s compared to the 94s.
So why the difference and should I care? What would happen if I remounted the bindings back 2cm on the 85s-effects? Bad idea?
