I recently bought a 2010 SG. Wind buffeting in my face was unbearable. Bought a 6.5 inch from Clearview, smoked with the recurve feature. What an amazing difference. Plus it looks virtually the same as the stock shield. Made riding a real pleasure...
I am still trying to deecide if I want the clearview or the klockwerks. Everyone seems to like the 6.5" so thats one decision made. Probably going to boil down to price.
I put on the 8" (or 8 1/2") clearview and love it. It's not going to be like a RoadKing or a windshield that goes up over your vision but it is better than the stock by far and I think it's perfect for the SG. It still looks good but it's also functional and not worthless like the stock one. http://www.clearviewshields.com/
I have a 9" dark grey recurved from Long Ride Shields. Great shield and much cheaper than Clearview. I had a 16" Clearview recurved that I sold and I couldn't tell the difference in quality.
