Replying to Where should I mount my bindings on my K2's???

Here is your answer! This is what K2 recommends...

"Factory Team Mounting Instructions:

With today’s twin tip all mountain, and park and pipe specific skis, riders are commonly mounting their skis forward from a traditional Mid Sole mounting point. The main benefits are increased control when riding or landing switch, and a more neutral balance in the air and on rails. For this reason, all Factory Team skis have a mounting scale on the sidewall running from a traditional mid sole mark, to a 7.5cm forward marking. Following is a general guideline for how to mount these skis. If you are uncertain, the best bet is to go conservative at first and work your way further forward.

0 – 3cm forward : All Mountain: If you plan on skiing mostly outside the park, and want the ski to behave like a traditional ski, you should stay on the conservative side and mount traditionally.

3cm-5cm forward : 50% All Mountain, 50% Terrain Park. When mounting beyond 3 cm, you will lose a little of the traditional feel of length in front of the binding, but with more tail, you gain the control in the air and riding switch. Seth Morrison mounts his Pistols typically at 5cm forward.

5cm-7.5 cm forward : If you bought the skis primarily for the terrain park, or are focused on riding switch in powder or in the backcountry, you may consider mounting your skis this far forward. While you may sacrifice forward directional float and stability, it’s made up for in the switch riding and landing stability and balance in the air. From 6.0cm to 7.5cm forward is where Chris Turpin, Pep Fujas, Mark Abma and Rory Silva typically mount their skis.

*Due to the position of the binding mat, K2 does not recommend mounting skis any further forward than 10 cm."
