I just returned to bowling after years away (also an old BR member "addik" - days of the late sawbones and excaliber, tenpinspro). Crazy to think I started 2 decades ago lol. anyway....
I have a question about Spare balls with slugs and IT's, they don't last in my hands. I roll over the thumb when I kill the hand for spares - end over end. Will going without slugs save the thumb hole from cracking? I know glue makes shells brittle but no so sure.
