Windshield and lowered seat height???

As the summer fades, starting to think about adding a removable windshield.
Have been reading the threads and one thing that is not apparent,,,is the
effect of lowering the seat height and the windshield height. For folks with short
ones like the boulevard,,,if it was on before lowering,,,,did you notice an improvement
after the change?

I'm thinking that the overall angle change should have moved the flow of wind.
