I guess it largely depend on application and where you live. I live in CA, so the sun is fairly intense in the summer. My fav. are Black Iridium Polarized and Ice Iridium Polarized for summer, and + red iridium polarized, Jade Iridium Polarized for less intense sun. Too bad Oakley doesn't offer a whole lot for the ice Iridium polarized lenses. What are yours?
