fritschi heel lock problems?

I've been having trouble with my fritschi diamir 2 heel lock-down mechanism. When the heel is locked down (and while skiing in deep snow), it seems snow can build up under the lock-down lever and release my heel. This has happened maybe 5 times in two years, and once last weekend up at Paradise. A quick and dirty solution might be to put a screw into my skis behind the heel piece (not screwing it all the way in), and using a piece of cordage wrapped around the screw and heel piece to hold it down better. Of course this adds more time/hassel to transistions, but it may do the trick. Anyone out there have this problem and/or tried to fix it? Looks like the diamir 3 uses the same heel piece.

Maybe the heel piece is getting loose, so it's easier to pop up? No problems with my Diamir 3s so far...

I had the heel piece of my Titanal 3's come free once last year during one of my many falls. Not sure whether it caused the fall, but the end result was that ski's tip was buried vertically to the boot in heavy mank. Leaving my knee twisted to the point of near destruction. I couldn't move without putting further strain on the knee joint ???. Fortunately a friend nearby was able to come over and pull my ski out, thus freeing me. No problems since, but I know they're not perfect.<br><br>I was hoping to put a pair of Naxos on this year and use them as a dual area/bc binding, but the early word is that they aren't pristine in their design either. Supposedly Naxo had addressed the self-releasing heal lock problem of the Fritschis and they may have. What I've heard is that the Naxos have too much "play" in ski mode.<br><br>Maybe I should just learn tele and solve the technology problem once and for all.

Play with someone else's Diamirs and see if the heel lever has the same resistance as yours. <br><br>I believe my heel levers have come up during crashes.

As far as rando bindings go, I'd agree that the ideal binding doesn't exist. I wonder if the plate binding concept itself is flawed. For ultimate downhill performance a light alpine binding the accommodates AT boots would be ideal. Building tourability into the system would require some removable part, something like a cable to hold the boot against the toepiece. We'll have to see what designers come up with. I hope that they will try something radically different from plate bindings sometime soon.

Thanks for the replies...at least I'm not the only one having these issues. Seems like a little re-design of the diamirs may be in order. A little extra thought put into a way to actually make the lever lock, instead of just relying on notches (friction) would be nice. Spring-loaded set-pins? I'm going to try the cordage fix for now. I'll let you all know if it works and post a pic if it does the trick.
