i have the s912 Ti widebrake on my pocketrockets...and they've pre-released once...and my din is at 7 .... and i'm 6'1' 150 lbs...and i ski hard....and the only time they came out was on super-frozen-slush-icy stuff...the pocketrockets rule, and the bindings are sick..the only problem is the plastic casing around the brake...if you land switch, eject and land on your ski, you can break that, but they'll replace it no questions
