Which screen do you have, the full size Roadster or the shorter summer screen? What style of helmet do you wear?
I have the Roadster screen and buffeting was a real issue at interstate speeds. I cut it down several inches and am very happy with the results. Still get wind but it is not fatiguing even after many highway miles. I wear a modular helmet, w/o the face screen most of the year (also live in Florida). Interstate travel is much better with the face shield on the helmet.
As mentioned above, lowers on the forks have been used successfully by several people.
