The Power Groove Dry/R React bowling ball from Brunswick is designed primarily for bowlers buying their first performance ball. It delivers a tremendous amount of hook potential for the money. The Power Groove Dry/R delivers a better match-up on dry lane conditions. High RPM players will find the Power Groove Dry/R to be the tamest of Brunswick’s reactive coverstock balls, making it an excellent ball to go to on dry lane conditions. Low speed players who struggle to get the ball down the lane will find the Power Groove Dry/R creates more length, saving its hooking action for the back-end where it belongs. The Power Groove Dry/R also uses Brunswick’s DISC (Differential Increasing Side Cylinders) core technology which provides the largest track flare potential of any ball in its class. Your green and chrome pearl Power Groove is finished with a high gloss surface which enhances its appearance and reduces hooking action in the oil.
