Well, I road 750 miles behind my new F4 windshield this week.
I've tried Honda, Cee Bailey and Clearview over the past two years. The F4 is now my favorite. I purchased the 16" height, light gray, no vent at Don's suggestion. It seems to be the just the right width and height for me (5'11, with a RDL customized seat that has raised me at least an inch) and best of all I don't have to baby it when I wipe it off at gas stations. I received the windshield in four days. I highly recommend you give the F4 consideration before you waste time playing musical windshields like I have!
