Basically a fantastic park ski (with amazing graphics).
SO light, stupidly light, really poppy, just the right flex, fast, fun and nice and narrow waist at 77mm. You don't even know they are there when you are in the air, giving you a tonne of freedom to do what you want.
I haven't had much of a chance to ski this much so I will update when I do, but what I have done so far, I really like.
Centre mounted obviously, and they are like air underfoot.
I have seen them skiied really hard on piste too and I understand they work very well and go pretty damn fast. Edge to edge time is fast too due to the narrow waist, so you have loads of control. They are not stupidly flexy so that you wouldn't feel stable, they are just right.
However because of how narrow they are, I don't think they are in any way an off piste ski. especially centre mounted, and I wouldn't suggest you mount these skis in any other way!
So you might not want them for back country booters however as a park/jib/everyday piste ski, I would really advise you get a pair of these!
