Well, I first bought the Ferrari Blade with the polar ruby lenses and I LOVED them. I later picked up a pair of Half Jacket 2.0s as well. The Carbon Blade and the HJ 2.0 are the ONLY new Oakley glasses that I like and fit me well. The HJ 2.0s are nice, but the bridge is a bit thick and is a little distracting until your eyes adjust. Out of all the newer glasses that Oakley makes that I have tried...my nod really goes to the Carbon Blade. Aside from the Ferrari version, I now have the BIP and the polar ice version as well. I must admit, I like the frame on the Ferrari a bit more...it has a glossy finish, the BIP and ice models have a matte finish. I might pick up a pair of the +O red...I love the lens and the finish of the frame is polished to. If I come across the +O red and the PRIZM at a nice price, I will probably pick them up. I don't understand why I can't purchase replacement lenses from Oakley...you can buy aftermarket lenses for them, but you can't get Oakley lenses....you have to send them in for replacement, and who knows what that will cost. That's the only downside I have found with the Blade. Other than that, I love the Blade. It fits nice and snug around my head and they weigh NOTHING! I would not pay $400-$500 for them...you can find them for less than half that price in the right places. If you are looking for a new pair of Os, check out the Blade.
