Of the eight balls that I currently have, I guess I bought three from a local Pro Shop
and five on the internet. Where I live (and bowl) there are no real experienced ball drillers that really know their trade and there are no bowling coaches. The area a VERY rural area with the largest town within 75 miles having only 12,000 people. The town I live in is just about 2,000 people with one bowing center (6 lanes). My Pro Shop
operator/driller just started doing drilling about three years ago. Luck for me, I'm a full roller and there isn't much that can be done differently in drilling for me. He does a good job and has no problem drilling a ball that he didn't order because he knows that if he can come within 30-40 bucks of what I would pay online, plus what I pay him to drill the ball (with inserts) that I would buy it from him. Like may bowlers, I'm not "made of money" and cannot always afford to pay $230 for a new ball. I seem to buy 2-3 new balls each year and it runs into more money than I could afford to spend if I paid retail each time. If bowling were my only vice (I'm heavily into golf also) maybe I could spend more on bowling.
