roughly the same issue, givi screen +/- tobinators, i'm 6 foot & have the seat on low setting.
The noise is due to having the airflow around the helmet, which drops markedly if i duck behind the screen, i honestly have tried the screen with & without the tobinators for about 3-4 months = 1500/2000 miles, making small adjustments almost every ride out
if you lift the screen you get buffeting like being sat on a pneumatic drill, lean it back & the buffeting goes ( helmet in the airflow) BUT the wind noise increases markedly, the tobinators only help airflow on this screen when it's leant back
i've also got the MRA new touring screen where the 2 screen parts are roughly the same size like the old 1150 one. this does stop the buffeting due to the design, BUT because it's only as wide as the headlamp unit, you get loads of wind on your body, which is where the givi screen is loads better.
next is to try either the tall screen from Nippy's or the adv screen = mucho money. So far i've spent £200 without good results....
Does anyone else around 6 foot tall have a screen that works well for them?
