I bought my Radar's specifically for running and biking, and I am quite happy. The hydrophobic lens treatment is definitely worth the price difference,

Ah, makes sense. Thanks.

The golf models have the vents on them. I just got my set of the jet black/G30 iridium Radar Golf Path; I love it. Like everyone else has said, the fit is super-secure, and I love the way it looks. I'm a big fan of Oakley's organic design language (well, I call it organic; I'm not sure what they call it). I'm also not sure why the golf versions have the vents, since vents seem more useful for active sports like running or biking.

Sorry, forgot to mention, they're the Radar Golf Path, the smallest of the lenses available in the new model.

My new Radar Golf G30's. I absolutely love them. I'm so glad I waited to get these instead of the M Frame (not that those are anything to sneeze at).
