They switched to saluc manufacturing them roughly 20 years ago. Prior different manufacturing and formula.That's because most people don't realize that centennials and super amaranths ARE THE EXACT SAME BALL lol The only thing different is the classic way the centennials are colored. this has been discussed to death on this forum. . Even if cyclops were better pool players would hate them because we seem to hate change. Hell players still make fun of someone who uses a glove and they've been around for 25 years .
That formula and ball predates modern simonios cloth. All mud cloth or bar box cloth! FYI
