I have a pair of Hok 125's with universal bindings that I picked up for this season...
So far, so good. I'm not a particularly great skier (a few seasons of xc and no alpine, ever), but these let me get to some nice terrain without feeling like I'm going to eat snow every other step. As mentioned, they excel in heavily wooded areas and are great at breaking trail. They glide reasonably well, all things considered, and they climb like champs. I'm in northern CO and ski mostly off trail between 9-11K with these, with a nice mix of rolling terrain and steep climbs/descents.
I'm not the biggest fan of the universal bindings, but they work well enough. I think someone else mentioned they don't flex that well and I agree with this. And the control leaves something to be desired. If I were to do it again, I'd probably pick up the adapter plate and mount BC bindings. As for durability, too early to tell. I think the skin could become an issue at some point, but who knows.
Overall - totally worth it, in my opinion. I find myself taking these out most often and always looking forward to it!
