For a USBC certified event, the ball must meet a set of criteria, which is usually up to a 3 ounce difference in top weight and 1 ounce for thumb, left and right side weight.

Usually a ball without holes will not meet this requirement and need to have either finger holes or a counterweight hole drilled to bring the ball back to legal specs.
