K2 Sidestash failure (Again). Suggestions?

Hmm , I also have a pr of unmounted Sidestashes (first year ) that I'm ready to mount.
I wish the picture was a little clearer.
What can happen with metal layer is the mounting screws can thread bind and can actually force layers apart. Screws can also bind in binding holes. Proper drill size ,Proper hole clearance and taping are critical moreso in metal layers. Just saying it outloud to remind my self when I mount mine.
Thanks for posting your issue.

OK, I should have said "has little to do with it."

Seatown, it's possible that the design of the Dynafit toes (pin & socket) and smaller footprint deliver more torquing leverage to the topsheet, but a full-scale delam like that from toe to heel indicates some sort of major materials failure.

Valid and accurate point, I didn't look closely enough at the blurry pic to see just how far the delam propagated.

Good point here as well.  If they were mounted w/ a 3.5mm bit and not tapped i could see how the mount could have stressed the integrity of the skis sandwich construction and made them more likely to fail.

But as GregL mentions, skis still shouldn't fail like this. K2 should take care of you (again) but it would beneficial to hear back from you on how they were mounted so we can catalog it for future reference. 

Another ski to check out would be the Movement Trust (141 / 108 / 129 mm) tip rockered but full tailed ski.

Movement Trust immediately sprung to mind for me as well. I haven't skied them, but would like to. Great reputation for quality.

Thanks for the ideas, it definitely helps to have some field tested suggestions to help narrow down the list of skis to research and demo. I guess the silver lining of this persistant High pressure system is that it buys me some time to find a powder touring ski.

K2 = made in China - what do you expect?

Go US, get Voile Chargers: 134-110-123 at 171cm, a bit fatter at 181.

I had a similar delam last summer in very firm conditions high on Hood resulting in toe pull out on my home made skis, and a subsequent adventure retrieving it. I drew two conclusions from this. Dynafit screws are a little short for getting a good bite into the core. I ordered longer screws from slidewright to resolve this issue. Second, I was skiing with toes locked, as I didn't want to drop a ski. When the heel releases, as mine did in violent chattery ice it put too much torque on the toe causing the tear out. I think in your case Zack, you have already come to the conclusion that a different ski might be better for you. It looks like Dynafit and Sidestash are not compatible for you. If it happens with a different brand, I would have to start thinking the application is incorrect.
