Before taking slivery of my 6, I had the dealer install the OEM Tall Shield with vent. I have absolutely no regrets with that decision. No buffeting, at occasional speeds of 90/100 MPH' or annoying noises IMHO. The ability to adjust the vent in warm weather is great. No problem in hearing the stereo. I'm pretty much deaf so I adjust the volume to 15/16 and enjoy.
