Cents have "darts" and I think the tolerances are lower. Personally, I like the way they look, that's why I bought them. NOTE: They are both made by Saluc, so the properties must be pretty close.
I believe that both balls are equal in quality. They do have a teensy bit of difference in their appearance. What's appearance.... most players look like they are homeless..
Its six of one or half a dozen of the other. Saluc makes both, and supposedly from the same resin and tolerance.
Just like armchair rally car enthusiasts, the debate of which rally car STi or EVO is better, it boils down to personal taste. Personally, I like the design of the Centennials but like the spotted cue ball of the Pro Cup Aramith.
That being said, I wonder how IPT Tournament balls stack up against Centennials or Aramith Pro Cup? These balls are also made by Aramith
Firefox will come up with a warning because the secure site license (SSL) has expired. I can't believe Kevin Trudeau didn't pay his internet bills.
I'd throw the Aramith Tournament in as well.
Their appearance is close to the Centennial balls, they're made from a new material which is more durable and they just look good.
I only found "normal" sets with the purple 4, but the Tournaments are played as a TV set on the Predator 10-Ball World Tour
