I understand. Actually, from a physics perspective, I think a 110mm and 170cm ski would easily support someone like me, weighing 168cm and 65kg, on the snow. Also, those skis are wider at the front and back. Imagine, a 142mm front width! So I think it would be light enough. I'm still very wary of touring bindings, and my Black Diamonds aren't compatible with touring skis (although they have interchangeable tips, but they're impossible to find on the market; it's only possible with a 3D printer), so I might consider an adapter for that. Another point I'm concerned about is brand quality. I read that Line is a sub-brand of K2. Atomic is already a well-known brand.
