This is our 2nd location which is inside Kingdom Plaza(OLD NORMANDY MALL)at Kingpins Lanes. Greg has been drilling balls for over 20 years and guarentees all of his work! We attend all manufacturers ball drilling seminars in S.E.United States and utilize the latest drilling technics to maximize your ball's performance and taylor ball reaction to each individual bowler's needs. If your current ball is hurting your hand or your bowling thumb is bigger than your other thumb, then IT IS DRILLED INCORRECTLY and it is not "because the way you throw it"!! Please, feel free to call with any questions concerning your grip. Thanx Donna & Greg
