The problem with the screen I had was that it deflected the air perfectly away from my body and directly towards my head. Prior to fitting the new screen I had the Touratech add-on accessory which worked well as it wasn't quiet as tall as new the screen. There was more noise than with the standard screen though, even with this. I think it's just a matter of trial and error to see what suites you best.
