I ride in a full upright, touring position. This is my 3rd 'naked R', the two previous were airheads. I've been through 5 windshields, trying to avoid being buffetted above 70 mph. The best I've found so far is the factory touring shield, the tall one, but it's still not adequate. Anyone out there solved this dilemma? Know anything about 'Laminar-Lips' or other devices?
