I havent bowled in 13-ish years and started three weeks ago in bowl in two leagues so I have 12 games under my belt. I am currently using a Columbia 300 Power Torq that I bought 13-ish ago. Since I started I have a 180 average and getting better each week. My first challenge has been learning how to make adjustments to lanes from day-to-day as the oil changes. That 13 year old ball ig getting beat up and now I wonder if I should invest in a new ball. If so, any advice? How do I know about the additional holes that get drilled/filled??? Please help.
