i got a chance to ski these skis this summer at Hood.
the skogen is possibly one of the worst skis I've ever been on. it has no torsional stiffness, meaning it will wash out when you turn it, and you can't hold an edge on it. It feels like you're skiing with sneakers on and the edges are made of rubber.
the AR5 is much better. it actually skis like a real ski, and holds an edge. it's not the most stable at high speeds, but it gets the job done just fine.
now on the other hand, if you're looking for a big-mountain twin, go with the LINE Mothership any day of the week over ARMADA's ARV. The Mothership is super bona-fide. Light, maneuverable, stable. the ARV quite possibly sucks. so heavy. doesn't want to carve. impossible to throw tricks on.
