On my RS-S, the problem is that the clear instrument cover is almost perfectly perpendicular to my viewing angle when I look at the dash. No matter what kind of shroud you put around it, if the sun is over my shoulder, it's going to shine directly in my eyes. It's a pretty stupid design. The instruments should either be at a different angle, as on a lot of other bikes.
Either making the gauges themselves almost vertical...
