I'm 5'11, but long legged. I have to stoop or move forward very slightly to have calm air with the stock shield in calm weather. Any kind of wind and I'm getting a lot of noise. I need just a couple inches more on the stock shield.
I'm going to give the standard Aero a try. 4" taller than the stock. I think the biggest benefit will result from the pressure relief by having the big scoop at the bottom.
