I want to get a windshield for my bike, but I don't know how tall of a windshield i would need. I am approx. 6'2 and my choices are a 15" height, or a 17" height. I just want to know if I buy the 15" (which looks better imo) will I be happy with the windshield, or should I just go ahead and buy the 17" which doesn't look as good?? Thanks
