I also have the +2 but I'm 5' 8". With the windshield all the way down, I get a nice stream of air blasting at my chest and above but oddly no head buffeting (which is a good thing). I do however get considerable air flow in my helmet creating more noise, but with ear plugs, a non issue. At highway speeds, at the mid point setting, I get a bit of air flow and noise in my helmet but nothing intolerable. The best setting for me (at highway) is the fourth setting but the top edge is in my line of site, so have to keep adjusting with some through and some over.
