I'm alllllmoooost ready to pull mine off for the summer. When the temperature gets up above 40 in the mornings, I think I'll jerk it off of there. For now, it helps keep away the "blues." (Blue lips, fingers, etc.)
I don't know anything about the Memphis windshields, but be awfully careful trusting those fitment charts the catalogues show you. We bought more than one windshield that was supposed to fit Kay's bike, before we found one that would actually stay on the thing.
