Gday, I have the Clearview 23" with vent and recurve (get these). I'm 6'4" and am pretty happy with it. Only complaint, and its not the screen, the visor on my helmet is lose and it rattles it as I ride, if i use my open or close face helmet its superb.
Important thing to remember is that you need to be able to see just over the top of the screen for when its raining at night, I made adjustable mounts so it can easily be lowered for this.
Problem with trying to upload a picture of something called a clearview is its hard to see....
