I really like it and nice quality. 13" would probably fine for you. I think the sport is nicer but obviously doesn't protect the rider as much.

 

No doubt the sport looks better. I only will use it in cold weather so I want the touring.

 

Love the 2015 Roadglide. Had a 2006 for the 9 years before moving to the '15 Special. I had put on a Clearview shield on the 06 because the factory one vibrated at highway speeds. The Clearview was great. So when I bought this bike last year, I wanted something other than the worthless 'for looks only' little screen that came stock. But there were not any available except via HD, So I bought the HD 12" Windsplitter shield. It was better, but even the wife asked why she had some much wind. I picked up one of the first new shields for the '15 RG from Clearview. It is the medium height (I am 5'10") sculpted with a light tint. And it works as good (or better) as the Clearview shield did on my 06. The recurve of the shield throws the rain and wind over my head, the vision is good, and the shield looks good too! Highly recommended!
