My 75lb son has the Z10s on his K2 Bad Apples. They seem to be a great binding while skiing, but the problem he experiences is that he is not heavy enough to compress the spring in the brake when stepping in.
It makes the bindings extremely difficult for him to get into, and he often can't step-in without some help.
I was actually browsing the site for an alternate binding, when I read your question.
