Jim,
A couple of years ago I replaced the NNN-BC bindings on my fat skis with a 3 pin cable. I had a couple of ice plugs in the bindings and did not trust them in the backcountry.
I have NNN on my skinny skis and love them.
I suspect I fall a lot more than you - that might be the difference. <img src="/forums/images/graemlins/blush.gif" alt="" />
