Just bought the batwing from Memphis Shades got the 5" windshield with it seem to get alot more wind then the windshield I use to have. The question is will the 7 inch cut the wind substancially or do I need a taller windshield the that..

 

one of my co workers got one with a 9" and complains about the wind compared to his stock RK shield. he's looking for a 12".
