I'm 5'10" riding on a corbin solo, with a 14" WindVest. Awesome, totally awesome. My best friend (rides Kawasaki 1500 Vulcan Classic) rode my bike, was impressed with the 'vest, got a memphis shades slim, and hated it, had to spend more money to get lowers, still had problems, and by that time, he'd spent more money AND time trying to get to where I was in 15 minutes. I look over the screen in straight lines, through it in a curve, especially the hard ones.
