The Look PX 12 Lifter WB Ski Bindings weigh in at just 5.8lb per pair, and come with wide brakes that fit your fatties. With a DIN range of 3.5-12, this binding works for anyone from progressing skiers to aggressive experts. The 6mm of rise under the toe piece and 6.5mm under the heelpiece add leverage to aid rolling on to an edge, especially when mounted on fat skis. The PX 12's suspended heelpiece provides more lateral support and decreases the amount of energy lost between the boot and the ski, which means you get improved performance without exerting any extra energy. This binding also features elastic travel that delivers shock and vibration absorption while guaranteeing a timely release during a fall.
These bindings are great as far as a basic binding goes. I had these mounted on my Liberty KGB skis (all mountain twin) and have beat them up pretty bad all over the mountain. No durability issues, no release problems, and they're in good enough shape that I'm putting them on my new scott missions for a third season of use.
On the groomers, in the park, in the pow, no problems anywhere.
I agree with the other post in that you can't go wrong with look bindings! I have three different look models and they've all stood up awesome! Have the 14, 12 and a nova 10(?) version. 12 really seems the way to go as the 14 has more weight and I'm not quite as happy with them (140lb girl though so its a bit beefy for me!)
