I have the dart windshield that does what it says. Deflects wind from your body to make highway more comfy. I am 5'11" and for me the only issue is I blows the wind into my mouth. If wearing a helmet would be no issue. I just ordered to try the national cycle quick release screen as slightly bigger. Think this should be perfect. Will post when I try it out.

I also have fitted a Dart screen to my Storm and noticed on the first ride that my hands were not having to cling to the grips and my arms were not being stretched. Trouble is now I just tend to go faster! A definite improvement and it looks good
