Dual Lock 15 lbs Plug 1 Grip will be removed before shipping. Condition: The R4S Pearl felt stable on medium-to-heavy oil, and combined with the stopping power of the RAD-X core, I used it when I wanted to bowl with a focus on stability, such as in competitions. It was a reliable ball when the hook wasn't stable after going to the dry zone. #Bowling #BowlingBall #Ball #Storm #storm #Reactive #DualLock #Lock
