I'm an Asian. Here is my findings about Asian fits on Oakley.
Good: Monster dog, Twenty(XX), Unknown(Asian fit:jet black/ruby clear), Big square wire, Straight Jacket(It's good for a wide head), Minute, Dartboard, Half Jacket(International fit works for me), (Pro) M-frame, Racing Jacket, Crosshair, Warden, and Juliet
Bad: Gascan, Riddle(I tried international fit on and this model has an Asian fit which is hard to find.) Mars, Penny, Teaspoon(Don't even think about it.), Most Wires
I recommend you and your wife to go to a nearby O store and try every pair there. That is the best way to find a perfect pair.
