Interesting but I don't read that language, whatever it is.

Have you looked at these? http://www.altaiskis.com/blog/products/the-hok/

Nils Larsen, who I have skied with, was inspired to make these by his experiences in the Altai, where he believes skiing actually originated,

The Visus were not a bad ski, but junk boards with kicker skins are better.

Every nordic ski is a compromise. All 3 of those skis are probably fun in the kind of powder I skied at Whitegrass on 2/3 & 2/4, which is common in the interior northwest where Nils lives. I haven't used any of them but suspect that an adventurous snowshoer would love them, a skier, not so much.

I got a set of the Altai skis, pretty fun. Climb like a scalded goat, takes little getting used to the short tail. Slap some 3 pins on'em and slide.
