first off, the previous Pure was Black not grey. The difference between the 2 is the color, and teh outer shell. The Black was urathane, and the new burgandy one is a very mild reactive resin. Which is better? i happen to think that the new Burgandy is an allaround better ball then the Black Pure. The mild resin allows this ball to be thrown on light, or medium (if clean backends), and it provides a tad bit more flare to give a better move/reaction. It is all prefrence, but if you were going to buy a Pure, i would say get hte Burgandy for better value, plus i dont think u can find the black anymore.
