@Alexzn ,
You said, you have decided on the Shift, but can
@Rod9301 and I give one more push to reconsider?
I own the Shift. It is a great piece of engineering. However, it’s whole “raison d’etre” is 50/50 use, or backcountry freeride. You said you don't need 50/50, and you keep it toned down in the backountry. It is heavy, and awkward to transition. You also need to step out of the binding to transtion. It lacks a high riser. Ease of use is a big consideration in AT gear.
If you really feel that the binding is going to affect how hard you can ski, or you want the security of lateral release at the toe, get a Fritschi Tecton. It skis as well as a Alpine binding (=Shift), and also offers lateral toe release. However, it is ~150g/foot lighter, and has much easier transitions, and more riser heights.
If it was only
lateral toe release that made you lean to the Shift, get the Fritschi Vipec Evo.
Otherwise, consider
@Rod9301 ‘s point, the fact that Cody Townsend mostly skis the MTN binding, not the Shift, the discussion on Blister I linked above, the Outdoorgearlab AT binding review and many other sources. Light Tech bindings ski well enough for most people in real backcountry scenarios.
Light weight, ease of use and reliability, are more important than ski performance of a binding.
Think of the difference in weight between a Shift and a ATK Raider 12 (
https://blisterreview.com/gear-reviews/2020-2021-atk-raider-12-majesty-r12)(350g): That is around 500g/foot. That‘s the difference between a normal, light resort ski, and the lightest touring ski! Which combo do you think will ski better in poor snow, resort ski and tech binding, or touring ski and Shift?
@Brock Tice discussed the effect a lighter set up had for him:
I started touring this past spring and have had an AIARE 1 class and probably eight uphill outings including both inbounds and backcountry. I am currently skinning/skiing with 2019 Blizzard Rustler 11s on G3 Alpinist skins, Atomic Shift 13s, and Lange XT Free LV 130 boots. I'm a bigger guy...
