Had mine prerelease too in deep powder last week (not locked in). I was leaning way back to keep my tips up and when I turned the ski just went on it's own little trip (thank god for leashes). I'll lock them down for the hairy descents or on really hard/crappy ice when I'm likely to flex the heal prongs things out of the boot's fittings (it has happened on a few occasions), but under normal conditions I like the idea of the skis leaving my body when called for and they do that just fine. Even with my DIN set to 6 they don't normally pre release - I'm 5'6" 145 BTW
Thane and I just downed a few pints discussing the benefits of a Marker Baron toe / Dynfit heal monster binding. No wonder we can't pick up women in bars :
Thank you climerdave, you have no idea how grateful I am for your post. I was beginning to think I was the only person who had had Dynafit pre-release and was in some obscure circle of hell where only MY Dynafits pre-released.
