Frame: 11-749
Lens: Clear

Pros: Looks, design, style.
Cons: A bit heavy, screws tend to loosen easily.

These were one of my first Oakley RX frames and I still have them. They are a bit heavier than more recent designs, but still look good and function well.

Frame: Black Ice

Extremely well designed, the combination of unobtainium on the earstems and spring-hinges allow the glasses to rest very comfortably on your head, the lens coverage is excellent too for glasses that aren't oversized

Frame: silver
Lens:
These look great, and the spring hinges are awesome. Downside is a bit if weight, probrably since I'm used to wearing plastic frames. But they are well built and feels sturdy enough to take some punishment.
