One of the guys I was out with has the Karakorum system on his split. He really liked the performance on the down with it. For the up, his initial thoughts were that it wasn't really any difference from a set up with Sparks. Overall, it's a pretty impressive system. I think there are a couple of kinks to be worked out. More or less with the binder interface. Pretty minor squabbles. Though I may wait until next season to purchase the set up myself. I think I'll probably get the mid clips to use with my Voile set up. Those are pretty neat-o.
