I am new to the Oakley sunglasses game. I've been wearing Ray Bans for years. I stopped at my local SGH kiosk at the mall yesterday. I fell in the love with the Crosshair. The only model they had in stock was the Lead/Black Iridium Polarized. Very nice and hip aviator style sunglasses. I tend to lean towards brown lenses. Oakley offers the Titanium/Tungsten Iridium Polarized for $50 more. Are the titanium frames really that much lighter than the alloy frames? Is it worth the extra $50? Since I have so many brown lenses, I might as well get something different and go for the Black Iridium Polarized. Plus, I can get a decent discount on the alloy frame model at an authorized online retailer, so it's a great value play.
