Hay JayDub, sorry for the delayed response. I got the National Cycle V-Stream Touring windscreen from Revzilla. It was the tallest (22 inches) and widest I could find. I'm 5'10 and the wind turbulence is much improved. Still experimenting with the two tallest settings. Little to no turbulence at the torso are. There still some air moving around my helmet, but a great improvement over the stock. Its also easier to tuck and get no turbulence at all. The screen itself is very thick with little to no vibration, a very well made piece. Easy installation with stock screw holes pre-drilled. The screen would look kinda silly if it were any taller, and I think still looks decent in the middle position.
