from my experience fks brakes do the exact same thing more often then any other binding ive had. the key is to get the width jut enough to clear the ski. if they are too fat this will happen to most bindings.
Yeah, m11's are awful. I've got a pair on my invaders, and while they work, because i'm a light rider, i had to raise the DIN way up because they were prereleasing on even the lightest landings.
