I HAVE BEEN A BOWLER FOR 57 YEARS AND HAVE BEEN DRILLING BOWLING BALLS FOR THE PAST 10 YEARS. I REALLY ENJOY THE ART OF DRILLING A BOWLING BALL AND LOVE SPENDING EXTRA TIME WITH EACH PERSON TO SEE IF THEY ARE HAPPY WITH THE RESULTS. I ALSO REALLY UNDERSTAND THE SENIOR BOWLERS AND HOW THEIR HANDS ARE EVER CHANGING. I RE-MEASURED A GENTLEMAN, AND NOW HE HAS INCREASED HIS AVERAGE 15 PINS AND HIS THUMB IS NOT CALLOUSED ANYMORE. HE IS VERY HAPPY!! I HAVE GONE TO MANY SEMINARS AND KEEP UP ON THE NEWEST TECHNIQUES, AND HAVE LEARNED FROM DIFFERENT PROS AS WELL AS PRO SHOP OPERATORS. PLEASE CALL AND CHAT ABOUT HOW I CAN HELP YOU IMPROVE YOUR GAME.
