About two weeks after bringing the bike home and after much research on this site and other resources I decided on an F4 Customs 16" clear with Honda vent installed. I'm 5'10" and have the stock seat for now. I'm very pleased with this setup. I look through the screen about 2"-3" from the top. Usually run the vent one click open as it gives a little air to me and provides almost zero buffeting and back pressure. If opened fully or one click from fully open it gives very good air movement to helmet vents and my chest. ( I wear a Shoei Quest ). Clean with a cotton towel and Meguire's Quick Detailer. Cleans up crystal clear with no scratches whatsoever after several months of use. Kind of pricey but well worth the investment.
