I'm looking to purchase a pair of Pit Bulls, but I'm not sure how well the color will stand out. I'm deciding between grey smoke/slate iridium or polished black/black iridium. They both have the silver Oakley logo. Will the grey be a shiny grey or a dull grey? I like the polished black because it shines more, but I have to pay a lot more for polarized lenses. Which color stands out more in your opinion?
