I think the Windsplitter looks FANTASTIC on the bike. The curves just flow with the front fairing and really improve the looks. If you're running a stock RGC shield... you are taking a LOT of wind straight into the face (been there, done that). This Windsplitter would be a major improvement for you and IMO add to the appearance of the bike.
I think the middle portion of the Windsplitter is about 10.5" tall from the top of the radio housing. It does kick the air up and push it over your head. I think the sides part the wind around the shoulders, but from there it wraps around the driver. The majority of my riding is two up distance (I have the RGU) in all kinds of weather. I wear a half helmet and it was fine for me. But last spring was a wet one and my wife didn't like how the wind rapped around me and into her, so I changed it back to the stock shield for our first trip and just never tried changing back. I figured I should bite the bullet and sell it.
