I have the medium height aero screen and the deflectors on the fairing. Big improvement over the QEM 990 stock and tour screens. Testing the Aero setup I extended the height with a clamp on shield extender and found that increasing the height did cut down buffeting. I don't run with the extension as the clamp is in my line of sight.
I mention this to provide data for your windshield quest. Height is a factor in decreasing buffeting. At least with the Areo and stock. Yea I know that we want a screen designed lower for off road and aesthetics. Thus the design needs to get rid of the buffeting but not be too wide or to tall. Your task is difficult.
I tried to make cardboard mock ups and ride to test but gave up. If for some reason I decided to tackle the screen buffeting problem I would get a wind tunnel, a bunch of Plexiglas and a glue gun. Then cut things up and glue together mock ups to test all the various configurations.
Lots of folks have tried to get a better screen and seems that the Aero helps considerably but is far from perfection. I use it because I don’t like the buffeting and live with a somewhat goofy screen. Good luck to your efforts and I will be watching your progress. If you get it right I am a customer.
