When we purchased our shapes, the wing was not available. Hell, when we purchase our first shapes, the only shapes they offered were the cube, wedge, ramp, and the stage. They have come a long way in the past few years. The wing does look very interesting, so if I had to purchase one or the other, I would probably say do the wing. You could use it "like" a wedge, as long as it doesn't roll away from you.
