I am 175cm (5'10). At the moment, I find that the original screen seems to do an OK job. At over 200kph, it does not make a difference whether I crouch or sits normally so Kudo to their wind-tunnel testing. Now I am looking at either the MRA Race (a bit longer than stock) or Sport one (curved lip). Has anyone around my height has an MRA screen and how do they compared to the stock one. I'd hate to get something that has more turbulence than the stock one, and prefer that the wind hit my chest than my helmet.
