Bought this ball used off Ebay just so happened that the ball was drilled lefthanded and was exactly my span what luck that was and only had 5 games on it. I was going to sell it but decided to give it a shot. I used it on league night and all I can say is WOW this ball hits like a truck. Even if you miss your mark this ball will recover. I have gone from a 205 avg. to a 215 with this ball. It's the first ball out of the bag and the last one in. I likethis ball so much that I bought 2 more undrilled and put them away.
