AV8, hi, have been using Randolphs for about 5 yeas and find them great. Had Ray Bans prior to this but I found the Randolphs better.I've got a pair of Concorde in the grey/green and find them relly good for flying. I am going to try the tan ones in the aviator style next, but these ones I am using refuse to break or fall apart.
I rang the guy in Melbourne who distributes them(found him on the web I think),he originaaly advertised in a union newsletters but he is most unhelpful. Give him a miss.Try Randolph NZ they are most helpful and are cheaper than the Melbourne guy, <a href="http://www.randolphsunglasses.co.nz/index.html" target="_blank">www.randolphsunglasses.co.nz/index.html</a> Hope this helps.
