I had the smoked one on my Advantage and it was hard to see in certain light conditions so I switched to the clear and they worked great.
Of course they caused some problems when I was trying to squeak every mph out of the Advantage and the wife would put hers up. Always got my hand belted when I tried to put hers down.
Got my new flaps on and they work great. I forgot to warn my wife about the sunglass suck factor. Add 80 to the price of the flaps to replace a 1 day old pair of Von Zippers. stI personally don't like mine. When I put them up, the turbulence from the wind sucks my sunglasses of my face.
