I use two different wings on the skis that I ride. I bought a thin stainless wing from Schnitz that is shaped pretty much like the average aluminum wing that comes on every ski I have ever owned or seen. Because it is thin stainless it has narrow profile and even more so after I removed the stamping imperfections and excess machine bolt material. It worked well on my 69" Sixam but not on the 67.5 Sixam. I tried it on the A1 but just couldn't like that ski other than it was very predictable (stopped before I could get to four ball at -35 almost every time). It likes being on the 68" MPD. I think the narrow stainless wing allows a slower ski run a little faster from the second wake out. So, if you have a ski that needs help shutting down to change directions stick with the thicker aluminum wing. If the ski won't go to the finish of the turn without hanging up or getting too slow then use the thinner wing. Where does the wing fall in the adjustment scheme of things. Locate bindings stock, set fin stock, install wing stock; then, tinker in that order until it works for you. After you are done, go back, make some changes and see if there is room for improvement...
