This is absolutely true "on paper", but in real world play, if they were all colored and marked exactly the same, I honestly do not believe I could tell the difference between Super Aramith Pro, Centennial, Tournament, or Arcos II. On a HOME table, I do not believe any of these top tier sets performs with enough difference to even be discernable by a professional player. They are all fantastic. I would suggest anyone in the market should choose among these and pick the set they like the most aesthetically. I own them all, play them all, and really like them all. The only possibility for me, and I would actually like to be able to test this, is that I DO believe the Arcos II set SOUNDs different on break and hard strike than any of my other sets, but maybe that's just my imagination.
