Mine is a DX bottom-stamped Roc, the 2nd disc I ever got (along with an Aviar, after playing for almost a year with only a Shark), probably circa 2001 (RIP Disc Landing).
I bagged it faithfully until last year, and only took it out for fear of losing it (sentimental value and all that).
Up until about 2 or 3 years ago, my bag was predominantly discs 10+ years old. Elite Pro X2, 2002 CFR XS, 2001 Am Worlds MRV, Elite Z Putt'r, 1.4 JLS. I threw what I knew, but what I didn't know was how much better I would be choosing discs that fit my style, rather than trying to make my style fit the discs I was throwing. /end ramble
