My buddy has the Bell photochromatic shield and his complaint is that it doesn't tint enough.
The GT-Air sizing is all screwed up because of the additional visor... for me. I don't fit the medium (too small) or the large (yup, you guessed it. Too big.)
I'm using a RF1100 with a light tint pinlock... it's does "ok" day and night but leaks during heavy down pours... which hasn't been a problem this year. (we're screwed)

Going through the Alps, in and out of tunnels, in and out of the shade of high peaks and steep cols convinced me that a built in sun shield is 100% the way to go, and I'm not going back. As to which brand, you're on your own.
