I go through glasses so fast there's no way I could ever spend big dollars on a pair, and I'll never wear Oakleys (it's a marketing/image thing, I know they're great glasses). The Smith's would be really nice though.
At the moment I've got a pair of Euro's I wear everywhere. They're great, fit well (which is the most important thing for me) no distortion and they were cheap. They're wire frame jobs though so they're not real riding glasses. I had another pair of great polarised Euro's which were brillant for riding, until I managed to snap the frame taking them off after a round of golf (yes my head is big, the boys at Bell list me as "bucket head"
). I think there was a crack in the frame or something though. I'm gonna see if I can get another set though coz those glasses were great. They're called "ocean", weird looking frame finish (bit garish) but I didn't have to look at that side so I don't care.
