Roto Grip is one of the best bowling company in the world with top tier bowling balls and equipment, just watch the PBA on tv with the top bowlers with roto grip and storm equipment. Don’t forget that Storm and roto grip are the panther together. For the past 4 years i have used all different brands of bowling ball and products and i found out that roto grip is one of the best. Their bowling balls hits hard in the pocket, you know what you are getting when you buy their bowling balls. Their equipment last a long time and their bowling balls for me have not crack. Sometimes bowling balls will crack and my roto bowling balls have not cracked. What ever ball reaction you need with a good price, with durability, high quality, always making better equipment, always give the customer what they want, hard hitting, you can’t go wrong with roto grip.
