for you guys with the buffeting problems caused by the shield, go for a ride and at 55-60mph put your left arm across your chest like a salute and see if that fixes the helmet buffet and watery/jiggly eyes and trying to lift the helmet. if so, go to Jack Halterman's Leather AeroVest, windshielding accessories for bikers, motorcycle riders and watch the video, problem solved and pretty inexpensive too
Darn nice quality too and they work well from first hand experience.
