A friend of mine who works in a bowling alley saw a Reign Supreme laying around all summer and no one threw it or even moved it. All the leagues have already started and it still hasn't been touched, so he decided to give it a throw since it fits his hand. He hasn't shot under 700 with it yet with a 298 last Thursday. Last Sunday, he let me throw it for a little while and I absolutely love it. I notice the Reign On also had the CAM core with a hybrid cover. I am not a technical person, so I am wondering how close these two balls are? The reaction I got out of the supreme is making me reconsider my Primal Rage...
