Depends on what you want from a windshield. Some, as above, like the short style. You get wind in your face, but it's non-buffeting. Depending on your helmet, may be loud, even with earplugs. Others want more protection, and go for a Clearview, which is wider than most, and keeps wind off the arms better. I tried several shields: OEM, Clearview, Laminar combo, and now Rifle. I felt the Clearview was too large. I didn't care about wind on the arms and shoulders. The Laminar Combo still didn't keep the wind out of my face, although it did feel sportier, and improved the MPG. I was looking for a shield that I could look over and still stay out of the wind. I am now using a Rifle+6 with a Laminar lip which does that job. Still a little noisy, as wind comes around from the side, but I'll stick with it for a while.
