Smith sunglass lens recommendation

[dudemanspecial]

I'm looking for a new pair of sunglasses for low light conditions. The Smith website shows the Guide Choice model can be configured with the Techlite Polarchromic Ignitor lens (12-30% VLT) There does not seem to be an option for a non-polarchromic ignitor lens. There is also a yellow lens with 33% VLT. Is the Ignitor lens color specifically the reason folks (who recommended them above) like them?
Also, I want glass lenses partly for the performance aspect Pcray talked about but also for abrasion resistance. In some places Smith seems to say that Techlite is a glass lens. Is that correct? (@Pcray?)

Smith has changed their lens lineup quite a bit over the last few years.

The low light Ignitor lens that everyone used to love doesn't exist anymore. The only true low light option is the low light yellow glass lens. I have a pair and they work well. They do fog up very easily, I haven't found a good way to prevent that, but haven't tried real hard either.
