In the 2002/2003 timeframe, CE Classic Rocs were made in a domey mold which is similar to a DX Classic Roc:
Since 2004, CE Classic Rocs and Champion Classic Rocs have made with a blunt edge mold similar to a Ching Roc with a lower parting line, which makes it somewhat more overstable and more importantly, reduces glide:
Imo, the latter disc isn't really a Classic Roc at all...it really flies nothing like a DX Classic Roc with the flight pattern we've all come to know and love. Is there any chance that Champion Classic Rocs will again be made in the old style mold? I absolutely LOVE these discs because they offer all the flight characteristics of the DX version with increased durability - I tend to beat up my DX Classic Rocs relatively quickly.
