I sprung for a new pair of Nordica Speed Machine 110 boots over the weekend. A big part of my decision was a better fit over my old boots. They are 1 mondo size larger and the sole length is 6mm longer.
So they do not fit my bindings as they are an an adjustment is needed.
Initially I thought I would take the skis and new boots to shop to have them just do it then I looked at the bindings and it appeared pretty straight forward on both of skis: a pair of Volkl Unlimited AC 20's with an integrated binding; and a pair of Mantra's with Rosingnol 120 XL's.
The Volkl Unlimiteds have Marker bindings that have a screw on the back of the rear binding that when turned just slides the back binding forward or backward on it's track. About 3/4 turn made the difference (9 clicks as it clicked when the screw was turned), and the boots fit.
The Rosingnols bindings have a small lever that when depressed moved the rear binding forward or back and thus this change was amazingly easy too.
So now I am thinking I am done. The DIN or other screws or settings were not changed so other than moving the mid point 3mm (backs bindings were moved 6mm) nothing else was affected. The Volkl Unlimiteds were initially mounted 1.5cm forward anyway so I am thinking I am about 1.2cm forward now in the case of the Mantra's which were initially mounted right at mid point I would be 3mm behind for which may help on snow days a small 'smidge' which is when I use them. I am otherwise a front side skier.
Is my thinking about right? I am thinking since no other changes were made just the moving back the back binding 6mm should not raise any safety concerns either.
