? I can't give an authoritative answer, but I would have to agree with what Stephen says.? If you want the AS Airfoil, sell your Diehl Skins. While the AS series air foil is a nice design and undoubtedly a much better refined airfoil, there's nothing wrong with the RAF-48 if you want to go that route. My KR has the Diehl Skins and RAF airfoil since it predates the development of the AS series airfoil.? It's no slouch in performance even with my heavyweight lard butt in the seat. However, if I was building a new KR today and had no parts on hand for the wings, I would definitely build it with the AS airfoil. ? -Jeff Scott
