Bill,
I agree. That's why I want a Windvest. I could lean mine back more since I have about 1.5" clearance between screen and speedometer, but it creates a horrendous updraft thus magnifying the buffeting from below. Memphis Shades and National Cycle both make nice sprortscreens that would better suit our rides. HabuBA has a WindVest, his bride, AmyLee has a sportscreen. Maybe they are the ones to ask.
Ya'll Ride safe,
Dennis
