I use the Puig Touring Screen with the Puig Deflector. I'm 5'11" (Over 6'0 with my boots on). I keep it in the middle position. No buffeting, very quiet. I am able to ride with my visor open pretty much all of the time, even on the highway at 80+ MPH (although I dont recommend doing that regularly).
I hope you find a solution that works for you.
