fastlane -- Balance holes are seldom if ever used to bring top weight into legal specs. Your balance hole was probably used to bring the side weight into legal specs. That does not mean you have 3 oz of top weight or even that the ball started out with 3 oz of top weight. The box that the ball came in would have the undrilled top weight on the label. Your pro shop must have weighed the ball after it was drilled, ask them what the final weights were. -- JohnP
