So, it's time for me to get some new Rx glasses and I really want some Oakley frames. I prefer low profile frames, like wire frames, semi-rimless. I really like the Keel frames in chrome, but the reviews on oakley.com say they're really fragile and have several design flaws. Aside from the Keel, I like the clubface in pewter, lizard in brushed chrome and the jackknife 4.0. Anybody have any thoughts on these frames, or similar wire and semi-rimless/rimless? I work in warehousing, so I don't want to buy something flimsy.
