You know it's going to be very rider dependent. I have zero tolerence for buffeting, and for me, this shield eliminated it. I'm 6'4" tall, so I was always in the windstream regarless if the shield was up or down. I found the windsteam to be very smooth. The only way to be totally quiet is to have a shield tall enough that you create an air pocket. For me, having the adjustable spoiler is a superior option over other shields.
