The difference between High RG (radius of gyration) and Low RG bowling balls lies in their core designs and resulting ball motions on the lane.
High RG bowling balls feature a core with the mass distributed towards the coverstock, creating a higher differential between the × and y -axes and promoting a more controlled and smoother ball motion. These balls tend to delay hook potential and provide more length down the lane before making a more gradual backend reaction. In contrast, Low RG bowling balls have a core with the mass concentrated towards the center of the ball, leading to a lower differential and a quicker revving action. These balls provide an earlier roll and a stronger and more aggressive hook potential, making them ideal for creating maximum hook potential on heavy oil conditions or for bowlers seeking a quicker response to friction. Bowlers choose between High RG and Low RG balls based on their desired ball motion, lane conditions, and personal preferences to optimize their performance on the lanes.
