Tecton FTW
Yeah, I'd make my choice between the Tecton and Shift based on cumulative durability assessment just before purchase, and maybe reviews of function for overall alpine including groomers and bumps vs lift-served sidecountry/backcountry only.
I like my Hagan Core/ATK Raider 12 bindings better than the plethora of other AT bindings I've used for alpine touring/backcountry. Not only are they lightweight, the heel allows some travel, flexing. I don't think I would consider using them on the groomed lift-served, especially giving the lightweight skis they are on (100 mm waist but only 5 lbs 6 oz for the pair). I think the two above would be better given their design an release functions.
