My '06 has had four different windshields now. Stock, Cee Bailey, Aeroflow (medium) and now Ca. Scientific (large). IMHO the CA Sci is the best of them.
The cee bailey put an irritating stream of air right into the face shield area at a variety of heights,and not good for the passenger. The aeroflow was better, but had more buffeting and back pressure issues than I liked. I kept experimenting with diverting or blocking air flow at different points on the shield and the laminar lip. Still not happy. Despite a lack of feedback about the Ca Sci windshield, I thought I would give it a try. I only live about 2 hours from their office, so I paid a visit to Mark Lawrence. He was quite helpful and we mounted the large size. In hot weather, I am thinking a medium would be better for more flow to my chest on the lowest position, but overall the large is the best for me at 5' 9". Greatly reduced buffeting and back pressure both. I am finally happy. He doesn't advertise, all word of mouth, so I wanted to post here with my results and encourage people to try his windshield.
PS He makes a small wind diverting clear shield for under the mirrors. It reduces the wind that hits the passenger dramatically. My wife said in the hot weather, she liked the extra air, so we will save those items for more chilly weather rides.
