Mr. Tamer I see the last few balls drilled have been 14lbs. Have you noticed anything pro or con with this? i’m pushing 60 love bowling but my 16 pounders are a tad heavy and my ole left arm she ain’t what she used to be. So I’m very curious with the 14 lb experiment. A video about this would be so helpful for many of us thank you sir.
Take a read of this article I wrote a while back. http://tamerbowling.com/bowlingball-14-vs-15-pound/
@TamerBowling Thank you so much!
