Justin Bergman posted on facebook, today, or yesterday, saying this.
"I remember playing Shannon Daulton in final 4 of Derby One Pocket 2-3 years ago and we went to lag and his lag crossed over to my side. No joke the ball rolled off like a foot and a half lol. Table was level it was these balls. They gave us a set of Aramith to use. Thank God people are starting to realize this. Only in pool do we play on shit equipment in the biggest tournaments."
He then showed this post from "Scott Frost", and "Chris Renfro", showing some Cyclop balls that were split down the middle, and saying that Diamond is going back to using Aramith balls again.
