I also have my Memphis Slim standing almost straight up and down to stop the buffeting. If you put your hand up to your face and follow the wind flow, I think you will find it's coming up around the tank and not from over the screen. I've heard that a set of lowers stops the buffeting. I'd like to try a different idea. I'm going to order a Memphis Shades Pop Top. Hopefully it will have different air flow characteristics.
