I've owned a few pairs of ray bans and recently bought a pair by randolph engineering. I'd buy randolph's over ray bans every time in the future.
I own both and like both. It's more a question of which frame is more appropriate for whatever I'm wearing. Just curious why you think the RE ones are so much better?
For the record, my sunglasses collection (maybe should start a porn thread!)
For skiing - Cebe Walter Cechinel aviator shape with leather side panels
For running - adidas evil eye
For motor bike - Wiley X or Liquid billet aluminum polarized
For driving - Ray Ban Wayfarer
For everything else:
Randolph aviators in matte silver
Current RAF issue aviators
My Dad's RAF issue aviators from the 1950's
Ray Ban aviators silver with mirror glass
Ray Ban Gatsby metal squares in antique pewter green lenses
Ditto in chrome with blue lenses
