I've been skiing since early March this year on 174 Cho Oyus with Kreuzspitze bindings. Wow, they do it all. Climb like a feather, and handle everything from frozen chunky corn to powder amazingly well! They turn on a dime but feel very stable. If you get them, get the pre-cut Dynafit skins too. Excellent glide, plenty of stickum, and they climb really well. Plus they fit the skis perfectly and are a lot lighter than my old Black Diamond skins.
I got these a while ago and mounted them on some 174 Dynafit Cho Oyus. GREAT bindings. Super well made and they work as well as I could have hoped. I particularly like the fact that I can use a flat, middle or high rise (with the cool accessory heel risers) heel position for flats and climbing, something that no other AT race binding that I'm aware of will let you do. I also purchased the optional crampon attachment pieces which are works of art, as are the rest of these bindings. So far I haven't found ANY...
