I will put cutting the windshield down on my Batwing today. What shapes do you guys like for the top of your windscreen? My current one of the 12" Memphis Shades Batwing Windshield, it is very rounded at the top. I need to lower it about 2 inches so I was going to reshape it and not make it as rounded on top. What would be the reasoning most windshields are so rounded on top and not just a nice gentle arc?
