Installed a 10' light tint recurve from Long Rider and went for a ride today. Made a BIG difference. No longer do I have an 80mph stream of wind hitting my helmet above my eyes. It's amazing how well that shield pushes the column of air upward away from me.
The fit was perfect and there is no optical distortion in the recurve as with some brands. There is a small amount of distortion along the top rounded edge, however, extending maybe 1/4" below the edge. Being that I went with the stock height, I am looking over it anyway, so I don't see it unless I am looking for it....
YMMV
