This is a Windvest. I can bring it to WV to see if it fits your needs. It is small and slick. Much better and smaller than the barndoors. Clamps go on handlebars.
Clean air even when looking well over it. Ill pull it from storage and take some pics for you. It's got some scratches and dings from chasing the wolfs in Leakey. Does the job very well with little drag. You can adjust the back and forth tilt and height to suit you.
