I just had a run in with that binding tonight... It was of course the rossi 180 Pro version though... My team mate just got a pair. Din is 8 - 18. We were examining them and stupid me decided to clip the heel down... big mistake. Do not clip the heel down with you hands when the binding is not attached to a ski! My left thumb is in the strangest shapes i have ever seen now... kind of resembling the space between the heel piece and the bar that the heel piece clicks in towards... I think that the space in there is between 3mm and 4mm. This hurts a lot... to get your thumb stuck in there
: . Also, with the DIN even slightly increased it will take you and another person to get the binding to release... so i dont think pre-release is a problem
: . It looks like a good binding... although im not too keen on touching it anymore... at least until my thumb heels and regains some of its original shape... They are a pretty aggressive contraption, let me tell you. But once they are engaged, there is not a huge platform to get leverage on to get them to release - just a word to the wise...
by the way - yes that was foolish, and yes i did know better, and yes i did it anyways.
