Live and learn. I ended up getting the National Cycle wind deflectors after my last long highway ride when I realized there was a lot of air/wind coming from under the mirrors. I installed them today with the help of my 11 year old and took a short test ride. In the closed position they definitely limit the wind that hits me and should make for an even smoother feeling highway ride. The ratchet system is a nice feature for easy adjustability. I'm still not crazy about the looks, but it's function over form at this point and they really aren't very noticeable especially in the dark tint.
