How tall are you? Height is very important with windscreen modification reports. A lady on the Yahoo group is 5'7" and the Saeng edging on the stock shield worked great for her. I am 6'6", and the Givi screen gives me more helmet buffeting than the stock screen. It moved the wind flow up - but to the point where it slaps the top of my helmet, which is often worse than having the helmet fully in the wind stream.
