Hi Gang,
I purchase a symmetrical urethane ball for mom. She is a senior with slower speed,low revs and tracks very close to the thumb. Ball that I received was pin in 1.5 to 2.0"
I am looking for some suggestions on drilling this up. She bowls on a THS and naturally struggles with her reactive as the lane breaks down. I know this question regarding pin in drilling has probably been asked a million times, but I am looking and hoping for some knowledgeable readers to offer some advice.
Thanks for your help!
