I've owned (in order) Smith Bazookas chrome, (i think) Oakley Twenty'*, fire/silver (dissapeared from the car
), Smith Boomerangs red (left in a porsche @ car show), and The new Smith Diablo'*.
The oakley'* were nice, but 120 bux, and no better optics then the smiths. Coudnl't change the lenses either. My new glasses are on closeout @ nashbar.com right now for $50...
These have the best wind coverage of any I have owned, and don't fall off at all.
