Got mine installed this weekend. Well worth the wait. Feels like I am running a new ski. Lat year I rode with a -3.5, which seemed a little short for me when I was in the holds. This season I've been riding at stock length, and just didn't seem to be able to do anything nearly as well.
I got the -2 and am much more comfortable riding, and I don't suck as bad when I try to pull off the few lame tricks I can do... and the steering is much quicker as well. Best $80 bucks I have ever spent on a ski part.
