Batwing owners, I'm looking into getting one, and I would like to know what wingsheild to get. I have the stock seat, and I am 5'6" tall. I have the stock "short" Yammie sheild right now, and the wind hits my helmet 1/2 way up my forehead. I would like it to just go over my head, so I'm wondering what length of sheild to get. All answers welcom. jdadoug
