I was just wondering about all the different kinds of Rocs there are. I throw an 11x KC Pro Roc and a DX Roc. Is there any difference in mold or anything from the 10x to 11x KC's, or ones like the San Marino's? Thanks for the info.

This makes for a really good start if you want to understand the different molds...

I think a lot of the flight variance has to do with not just the mold, but how the different types of plastic cool, and weather they stay domey or flatten out. But I'm not an expert.

Thanks ethan, that clip helped me understand it all a lot better.

They're all the same.

That's why players carry 12 of them in their bag, because they all beat in differently, all fly differently, and you'll never know until you thow them. You could do the same with any other disc. Pick any disc off the shelf, buy 10, all differet weights and plastic types (domey, flat, etc), and then throw them A LOT until you know how to throw them and what they'll do. It's the player, not the disc. Don't get sucked into the overhype!
