The AR50 side wall on the AR7 is supposed to lower swing weight. Also keep in mind that the pipe cleaners have the race base. So if you don't want to wax your skis a lot, you should go with the AR7. If you are worried about stiffness, the THalls might be better, but they are more expensive if you don't want to spend the money.
