Ok you experienced goldwing riders...who likes their stock windshield? I am almost 6'2" and at the highest setting I find myself either looking over or slouching under to see. When I lower it down so it doesn't obscure my vision, my wife feels a lot more wind. I've been looking at the +4" but wondering if that is too high. Those of you that have the 4" how do you like them? Do you recommend a specific manufacturer? Do you hit your helmet on it when you get on the bike? I appreciate all your suggestions.
