To mess up other bowlers?
I have a modern day solid urethane that is the best ball in my bag. It's not the first out of the bag, but when it does come out, I wonder why it's not the first all the time. I'm averaging just under 218 with 26 or 27 games this season.
Anyway, when the urethane does come out, high average bowler playing the track seem to suffer in carry. Some even worse, they get over under. Some have made comments about me using urethane.
For 4 weeks straight, I started noticing my opponents all had carry issues when I start using my blue. All would switch balls and moved in, or whatever, to later find their groove back.
