Hey guys - first time poster...just stumbled upon the forum while doing some research for my latest pair of Oakleys. The site seems like a great resource. I also just discovered OakleySI.com (Standard Issue), where I've been granted access and will be purchasing my next pair. They have some great pricing and selections. I tried on a few pairs at SGH over the weekend and really like the Crankshaft and TwoFace models. Unfortunately, the Crankshaft model that I really want (Matte Black/Black Irid. Polar OO9239-06) is on back order at Standard Issue. Therefore, I am considering picking up their Covert collection Crankshafts (Covert Matte Black W/ Grey OO9239-12). The only issue with the Covert version is they come with a standard Grey lens and I would prefer the Black Iridium Polarized lens. Question: If I buy the Covert version, where is the best place for me to pick up some replacement black iridium polarized lenses that will fit the Crankshaft? I can't seem to find them on Oakley's website. Covert Crankshaft Alternatively, I am considering just picking up the Covert collection TwoFace model instead which already comes with polarized lenses (Covert Matte Black W/ Prizm Daily Polarized OO9189-26). Question: Any thoughts on the Prizm Daily Polarized lenses? What do you guys think of them? Covert TwoFace Both models seem to fit me very similarly with the TwoFace being just slightly larger. I really like them both. Depending on the price of replacement Crankshaft lenses, I would probably end up spending around the same amount of money in the end for either pair. These will be daily shades that will see a lot of wear. Which path would you guys take? Thanks for reading and I look forward to some feedback.
