Dan,
Just got back from 3,400 mile trip to and from Sturgis. We rode in rain, wind, high winds, sun, clouds, sleet, more rain and more winds. My wife/BSR was completely happy with the Cee Bailey (just buy it 1 or 2 inches higher than they recommend). She had no bad winds or buffetting and never once mentioned any issues due to the windscreen. I would buy another Cee Bailey today if needed. As for me, the only time I felt any buffetting was with some of the cross winds on the plains, but no windscreen will stop that side wind stuff. Windscreens are definitely personal preference, but for looks and performance on the road, I'm sold on Cee Bailey as is my BSR. For around town and below 60 mph, KW is the best.
Hope that helps Dan. Email me if you want more discussions, timaingram@hotmail.com
