I put the above screen on my 12GS last week and I'm very impressed! Turbulence, buffeting and wind noise led me to an Aeroflow last year. I love that Aeroflow, but, I was hoping to find a screen for the summer. I get really warm behind that Aeroflow, since it works so well.
Anyway, I was willing to sacrifice wind noise for a smaller screen, but, I wasn't willing to go back to getting beat up every time I rode my GS above 50 mph. This screen does a remarkable job. I'm extremely impressed. No buffeting. No turbulence whatsoever. Extremely quiet, for what it is. Tons of airflow. This is a great summer screen for me. Fits perfect too. It fits just like stock screen, plus the added adjustability for the spoiler really makes a huge difference.
