Is it possible for a cue ball to get "worn out", even if cleaned regularly? I've seen cue balls at bars that are obviously chipped etc, but this week I was getting frustrated, practicing on my home table and not being able to get as much spin/action on the CB as normal, and not pocketing as many balls as I do normally. I swapped it out for a brand new cueball, and everything was back as expected. The old CB has some marks on it from chalk etc that I cannot get out with normal cleaning, but no cracks or indentations... it is about 9 years old. Due cue balls have an expected life span? It's an Aramith ball.
