To me, windscreens are like eclairs. I like the idea of them, but ultimately I'm disappointed. I've ridden dozens of bikes with them, many of them aftermarket or adjustable. They all end up creating too much head bobble. Sometimes it takes a few miles before it bothers me, but it does eventually. The only time I am not bothered by wind is when I ride a bike with little or no windscreen.
Clearly you have never tried Madstad.
Running no or small screens is fine for short hops or low speed, but can get mighty fatiguing on a long high speed ride.
And it can stretch your arms!
