Well, I wound up buying one. And I can add my experience to this thread. The shield sucked for me. They made it taper down narrow at the front to be the same width as the little fairing/cover bit there. It lets a lot of wind in to hit your body and go up under your chin and in your face. I bought a piece of polycarbonate from home Depot and filled in where I thought the air was coming from, and it made it a lot better. I have a shield coming from Cal Sci now that should be about the same shape as what I wound up with , with my add on piece. Also tall enough to hopefully not need the spoiler on top. I'm taller than most, so I struggle with wind protection, but I think anybody would be unhappy with the win d the polish shield lets in at the bottom. I'm also going to make lower wind deflectors that mount on the forks to see if that helps. This add on piece was only an experiment and not meant to look pretty or be permanent.
