I put the baker hand wings on this past year. I was hesitant because I didn’t like the looks, but I use them all the time. Deflect air away during the chilly morning then adjust to pull air in when it warms up. I have risers so my hands are mostly behind the mirrors. I notice the change of air along my sides from my belt up towards my arm pits. It does also change some of the wind that blows on your back at certain speeds. Also I believe they are made in Ohio!

A side note. The template to mount the stops are for a full wing. I think I transferred the indexing line and flipped it over to work for the B. But it took some adjusting to get the stops and the tension correct.
