most common reason I have seen the cracking around the bridge are holes drilled to close together. And no bevel placed at the top of the holes. I have seen the bevel problem more with Columbia balls. A pro shop can drill it out and re plug and drill your fingers out I have done this with 3 of mine. All 3 had no bevel done on the first drill
