I have both the shorty and medium OEM windshields and I much prefer the shorty. Still get that dirty air from underneath but not as bad as the medium windshield is. The turbulence is so bad with either one of them I can't wear a half helmet because it shakes my glasses all around. Been wearing a full face since I got my XR 6 years ago because of the "tank air" and got so used to a FF that I won't go back to a half helmet.
