Familiarity: I've used it several times
I use these on resort when I have to, but I really try to push these into the backcountry. Wonderful to use. Very easy transitioning between hike and ski. These have a lateral release for alpine and touring boots, which the Guardian does not have. These are also very compatible with your ski's flex pattern. They have wonderful technology all around. Put in the extra couple bucks. Tyrolia, Head, and many others sell this binding-it's all the same binding. Keep moving forward. Comments/questions are appreciated.
