This ski is one of the quickest skis out there. I have a pair 162 and the radius is 11.5, my friend also has a pair but the are this year's SLX. We are the two best skiers in our confrence, and we live by this ski. Next year most of our teammates will be getting this ski. It doesnt matter where you're at, steeps or flats this ski will carve thru anything. It is a stiff and strong ski, but you have to get you speed up to carve on it. This is probaly one of the best skis that you could race on.
