...or any other full face helmet for that matter. When I ride with the shield fully open, I get the whistling sound of the wind passing in between the shield and the top of the helmet. At the exact point where I can lower the shield to stop the whistling, the edge of the shield is right in my line of sight. Anyone have any suggestions other than riding with the shield completely down? I like having it open when I am just cruising around the neighborhood no faster than about 30mph (and yes, even that slow I can hear it whistle!)
