She was using the w spring. Her normal din setting is 5-6.Quote:

Honestly, there are so many variables here. I double ejected full-vertical release on a snow snake earlier this year on Dynafits set to 10 for vertical release. I usually ski a DIN of 8.5 or 9.Quote:

Good luck on the rehab.
So sorry Kevo. Hope she heals up quickly. Sending good vibes your way.

As Cody Townsend said in a podcast or video I was listening to, "tech bindings are fucking dangerous."
Interesting, that's why they decided to create the shift! That way I double eject every time I drop anything > 3 ft.Quote:

so IME turning up 1 DIN like setting on a techs or any binding for that matter is enough to make or break on release
but U springs go up in 2 DIN (like) increments and whatever one runs can not be adjusted
but they are light
Not only did I tear my Achilles skiing an alpine binding, but it also released in the process.Quote:

As many have said... lots of variables at play.

In the same podcast where he says that he also claims that he was skiing the shift in his last msp segment before the shift was publicly released. He said he literally broke the plastic in half of his ski boots on some big cliff sends and didn’t eject while skiing the shift. Good listen on blisterQuote:

And points out that most people reporting pre-releases are almost always skiing poorly adjusted bindings. And that the Shifts are particularly particular about precise adjustments.Quote:

I wouldn’t trust any shift set up by most shops. Spyderjon I’d trust for sure. Leelau has the best description on how to properly set binding. Find it on newschoolers. I’ve found mine to be one hundred percent reliable since I set them up correctly.
There have been several instances of MTN bindings failing to vertically release and causing injuries buried in the Wildsnow archives. Its hard to say if this is just because the MTN is by far the most popular U-spring binding on the market and people are running springs too strong, but the reality is there are way more reported instances online of people getting injured in these situations with MTN bindings than any other binding. This is not an isolated incident, and I have not come across similarly scary reports from people with tech bindings with adjustable vertical release.
I helped my GF put together a touring setup last summer. She was able to get the MTN for $200 thru her work, and because I stress about this stuff I insisted she spend the extra $$ on something with adjustable vertical release. It was a tough sell but stories like these confirm my suspicions about the binding, especially for smaller skiers.
I'm a crappy skier and fall all the time. I have had multiple vertical releases in my Crests, and many vertical releases in the Ions I had before. I trust adjustable vertical release in tech bindings, and this issue is not shared across the tech binding spectrum it is specific to U spring bindings and perhaps it is specific just to the MTN binding that misrepresents its heel spring release values and has abnormally strong toe springs.

I took my GF to a follow up with an ortho today. She got an MRI on the achilles and also got her opposite foot looked at. Said foot has had increasing swelling since Friday and she can't put weight on it. Turns out the ER doc and the radiologist over the weekend missed that she's also got a broken talus in her other foot from the binding not releasing until she slammed her foot hard inside her boot.
She had a CT scan today to see if the talus is fractured all the way through or not. If not, she'll be in a cast/boot for 6-8 weeks. If it is, she'll likely need surgery which would be a major bummer since she's already needing the achilles surgery in her other foot.
Sorry about your girlfriend, Kevo. Sounds like a brutal injury.
My take on tech binding safety:
They aren't. Try not to fall.
My other take on tech bindings safety:
TUV certified tech bindings will release more consistently across different boots, but they still aren't comparable to alpine bindings. Still try not to fall.
My last take on tech bindings safety:
Speculation about which bindings are safer than others is just that: speculation. Do you know who popularized the whole "U springs are less safe" thinking? G3, whose Zed's weigh 100g more than MTN's for similar performance and, I'm fairly certain, don't sell nearly as well. Think they might be biased? (note that I own neither binding)
So go ahead and try to make the safest choice you can. If you pick Tecton/Vipec because they might protect your bones, I get it. Totally valid way of choosing bindings. But consider if you're basing your decision based on information that originated with a marketing department, and note that it doesn't mean much for a binding to be safer "in theory." Even if you manage to crack the code and choose the safest tech binding, it probably won't release as reliably as and alpine binding, so you should try not to fall.
If you aren't going to try not to fall, consider Shift, Cast, or if you are foolhardy, those silly Markers.
I think about this stuff differently than most people seem to.
The issue with tech bindings should be that they release when you don’t want the to... not that they don’t release properly. The design issues hinge around a lack of elasticity (and some inconsistency). Why do we assume a backcountry binding needs to have the same RV as a resort binding? Ski conditions are completely different. Hopefully you’re not mashing moguls in the backcountry. People who want one setup that works in both conditions are really asking for issues because tech bindings need to be cranked down to work in the resort which is super sketchy.
Essentially that means you run a lower RV than normal and see how low you can get while keeping your skis on in most conditions. People often try to compensate for tech bindings with poor retention (due to elasticity) by cranking RV the other direction.
The issue with the injury described seems to be that the MTN binding doesn’t release for lighter skiers because the RV value is higher than advertised. What I take from this is that a binding like that ATK crest 8 with an RV of 3-8 is good for lighter skiers.
Thanks for posting the injury news. Super sorry to hear that and fingers crossed for a single surgery.
In the same podcast Cody mentions that an ortho he knows in Jackson hole told him that since the proliferation of tech bindings he’s seen way more injuries. Also the la liste guys are hiking in CAST system and alpine boots with no walk mode. La Liste 2 will show them skiing 6K peaks. So no need for ultra light to tour. Just get in shape
Sucks for sure.Quote:

Not sure what the solution is for your girlfriend, but I wish her the speediest and most thorough recovery possible.
you can buy a binding that releases at " A Value " and attempt to ski TO that Value or buy a binding that you can adj to your skiing
Take everything Cody says with a grain of salt since he wants to sell Shifts. That said I believe him here, but the issue is most likely the proliferation of tech bindings inbounds, and especially people skiing inbounds with locked toes which I see a lot at Alta and is surely a thing in Jackson as wellQuote:

I think a lot of them don't know any better. Marketing doesn't help.Quote:
