Baker hand wings are the best! All summer, they helped bring air in behind the windshield. Now in the fall, I start a ride while it's cool, wings closed. After a few hours, it warms up, wings open. Heading home in the evening, cools down, wings closed again. I don't think they look as good as Flathead's wings, and I would really prefer them to have a second mounting bolt so they'd hold their position better, but I could never give up the dual functionality.
