Hm ... I called the warranty department yesterday, and they said that Asian fit and Standard fit Path lenses
are interchangeable, but arab_pete seems to know what he's talking about, and just looking at Oakley's product images inclines me to believe him:
Standard Path:
Asian Fit:
Notice the different shapes -- the Asian fit lenses seem to tuck closer to the frames near the hammerstems. It's similar to the difference between Hybrid and Sweep lenses for the M-Frame.
@arab_pete: do you have both sets? How do you know that they don't fit?
