Black line through the ProV1X label and the number 18 opposite the label. I like to keep it fairly simple. I want to be able to identify my ball easily, but I also don't want to be blinded my Jackson Pollock artwork either.
A buddy of mine used to have his daughters, when they were younger, draw all over his pellets before his tournaments. You should have seen some of these things. Probably could have sold them at auction as contemporary abstract art.
