Bought a yellow dx roc today with a flag stamp and noticed it has patent numbers and no www tooling. Its close to flat and stiffer than some i've felt. Is this old stock or is this the norm??
I don't think the tooling on the bottom of the Rancho Roc changed when a lot of other discs added the www. and removed the patent numbers.
As for the plastic, it's so much of a wash that you probably just got lucky that that particularly blend was a bit on the stiffer side and the cooling time was correct for producing a minimal dome. I was at Air Play Sports today and there were a few DX Rocs that were pretty close to flat and not as waxy as some previous runs had been, so maybe the newer blends of DX are coming out better.
