Its trial and error I guess, what works for one person doesn't always work for others. I changed from the small sports screen on my Vee to a MRA didn't work as well as I wanted so added a Madstad adjustable bracket. I'm happy with that option, no buffering and I can ride with my visor up on the motorway no problem. Others will say the Givi Airflow works well but I haven't tried that. I'm also 5 ft 10.
