Thought I'd chime in with my experience with the shield. I'm 5'7" and easily see over the top. I first set the shield at the same angle as the forks (if that makes sense) and it was fine up to about 50 MPH, but after that the buffeting on my helmet was annoying. I tried raising the screen and that helped a bit but the wind was still catching the top 2" or so of my helmet and rattling my noggin. So I tried angling it forward (steeper than the forks) and that did the trick. Now it's giving me pretty calm air, even at 80 MPH. Not that I would go 80 MPH

I feared that some stability would be lost with the steeper angle, but I can't feel any difference in handling at all. So, I am a happy camper.
