It doesn't seem to be as much of an issue as it used to be, perhaps because Freeride Plus has a thingy that prevents insta-tele. Fore, no idea.

Yes the pin does somewhat limit the bindings movement, and close examination showed the pin being forced forward when the ski was flexed. I set the ski up on 1.5" blocks spaced 46" apart and pressed down to bottom the ski, with and without the pin in place. Both readings indicated a force of 115 lbs was required. Next I increased the blocks to 2.25" and again pressed the ski down until it bottomed out. This time it took 155 lbs without the pin in place and 160 lbs with the pin in place. So the pin does somewhat stiffen the ski and place a load back on the heel piece. I have been skiing with this fix in place for about 4 years now and I weigh 155 lbs. My friend who weighs 225 lbs has also used this fix for 4 years (and probably 300 ski days) and neither of us has had a problem with the heel piece slot being damaged. I am not sure the current design change that Fritschi has incorporated would fix the problem I had. In all cases when my heel released, the locking device was in the unlocked position, indicating the heel had not been released due to extreme flexing. In all cases I had stepped into the bindings at the start of the ski day and was confident they were not subject to snow or ice build up. I am still not 100% sure what caused my problem but the locking pin has solved it for me and not presented any further concernss so far.

Touring on a daily basis, I really never lose my heel, in my mind the problem in heavy snow is caused by the lack of solid connection in the heel unit initially. The times I've insta-tele'd, there was snow in the binding initially that I just got tired of cleaning or couldn't clean. Some kind of attachment to secure the pin when not in use would really make this thing more user-friendly. Could be cool.

Craig, what's your take on that? Carl, the binding still has some movement with this mod. Craig, what’s your take on that?
