Hi:
I have the large model on my RS Venture. I also did some careful measurements and some communication with Clearview before deciding on this height. My main reason for selecting another shield was that the factory one was downright dangerous in rain. I could not see through it in moderate rain and stretching to look up over the shield was not a comfortable option when you do it for one or two hours. I am 6 ft, 1/2 inch tall and my normal line of sight is now about an inch over the top of the LARGE shield which is right about where I want it. In rain, no problems... I see clearly over the top. There is also less buffeting and wind noise for me and passenger. I realize that the larger shields provide better wind protection, but for me, I wanted to be able to see and continue riding in rain. Oh, and I also have the vent and love it. Leaving it slightly open reduces buffeting and noise even more.
