Let me explain. I've got a good pair of boots and skis, they've seen a hell of a lot of use, but I love them. The boots fit so well, and I can take my skis anywhere and really tear up anything. My K2 Public enemies were left over by a graduating kis at out school and up until this point I never thought I'd use a twin-tip ski.
Anyway, even when I demo a new ski you don't always know how it's going to be in all terrain. It is for this reason that I always stick with the top end all mountain ski, which has usually seen me right, but I do hate giving up any ski that has treated me well.
