Always used the Smith Blue Sensor Mirror lens for low light conditions. It was pretty consistently rated the best on the market for cloudy, snowy, flat-light situations. Smith is discontinuing this lens, however, and tried to replace it last year with the ChromaPop Storm (blue tint, 50% VLT). I tried it but didn't find it superior to my Blue Sensor Mirror (60% VLT). Apparently, Smith realized the problem and they are introducing a new ChromaPop Storm Yellow Flash lens (65% VLT) this year.
Did a back-to-back comparison in flat light/falling snow at Loveland today of my old Blue Sensor mirror and the new Chromapop Storm Yellow lenses. No contest. The ChromaPop technology worked as advertised in sharpening contrast (Oakley has a similar system in their Prizm line of lenses), and the yellow tint and increased light transmission created superb visibility. Blew the Blue Sensor mirror right out of the water. Highly recommended!
Best!
