I agree with
@Primoz , whilst a 11x+ waisted ski has a "cool" factor (and one can ski it in the Alps as well) a thinly waisted ski is more than enough 97% of the times here for AT activities. My powder skis are 106 mm waisted 10 yrs old Gotama with AT Baron bindings. Perfectly fine in the kind of snow I get at my resort, both on piste and off. This said, skins (which I do have, of course) are there for emergency only, the setup is still a bit too heavy for my liking, performing "regular" AT activities (with Tecnica Zero G GP). If you plan ski touring
@SBrown, then 88-95 (at the really maxmax) should do the trick, and offer versatility (not uncommon for
ppl here skin up in 78 waisted skis or even in race equipment, which is currently all the rage) what lenght, it depends on you. Me, I am targeting a 177 cm long, 88-95 waisted, witch specific bindings and boots; but first, wife needs to have her knee mended, then we will take on AT heads on, both of us.
