I'm in the middle of writing my Christmas list to Santa and I'm going to ask him for a Rifle windscreen. I just have a couple of questions for you guys.. First one is does any one think its a mistake getting one? The second is on sizing, is just looking over it good as a rule of thumb? Third is I THINK I want to order it in gray tint, has anyone have one tinted and could shed some light on pro's and con's? Thanks
