I replaced my 12 inch Windvest windshield with a 15 inch LRS. The buffeting is reduced but not completely gone. At 15 inches I'm seeing just over the top of the windshield (14.5 inches might have been better) I've only been riding with it for a couple days. I might try adjusting my fork lowers to see if it helps any more.
It is better than the 12 inch Windvest though.

Born in the deepest jungles of India, I was raised by a friendly bear, until I was kidnapped by a pack of unruly baboons who taught me the finer points of swing jazz, all the while being stalked by an incompetent python and an evil but mis-understood tiger... Ummm, wait a minute, that's the Jungle book, no I was raised just outside of St. Louis, But...in the deepest jungles of a middle class neighborhood .
