Thinking of getting one or two pairs of Flak 2.0s. Not the XL...the regular ones. Looking at the website, Oakley has the Flak 2.0s in all black with black polar lenses, and red with OO red lenses. I see they don't really have that many lens options, they do have a huge array of socks for them in different colors. Anyone know if there were any kind of blue polarized lenses made for the Flak 2.0s? Just curious what's out there. Thanks!
