What made you pick the 15" one? If I was going to get the Madstadt; I would go no smaller than the 13" but I wonder if the 15" would be akin to a barn door.
I also noticed in your trials and errors; that you had both the Clearview medium AND large windshields. The large still didn't do it for you? How tall are you?
Reason why I ask, is that I am still going through the windshield decision making process(s) and am not sure if changing out my current Clearview medium to a large; is the answer myself...
I still am trying to get my head around the ugliness of the Madstadt though.... maybe I'll get through that...
