Yeah, the change to the www core was only a few years ago. You still see the San Marino Aviar's all the time. They were in production with the San Marino core for over 20 years and the Aviar is by far the best selling disc of all time, so there is like a kajillion of them out there.
Off topic, Are there Rancho Aviars out there? I shouldn't generalize, but I've found anything with a www felt worse than others I've had or didn't fly the way I remember.
I had a DX Stingray that I gave away, and I rebought one later on that was the www mold and just felt bad. It also chunked up first tree hit.
