trjam,
I recall that when I bought my windshield, it was recommended that the top of the windshield should fall somewhere between the tip of your nose to the bridge between your eyes. It seems that in your signature pict, it may be too low for you. I am wondering if raising it 3", as you mentioned, that some wind might still get in around the headlight.
I was getting a lot of buffeting before adding the windshield and much less after installing one. I also added lowers which also helped a great deal. I angled my windshield back further when installing it.
Hope this helps - bikervas
