This option is best for recreational bowlers who are getting their first bowling ball or have not had a ball professionally fit for them. Having a ball drilled at your local pro shop can cost as much as $50 or more. Our standard drilling options come in five basic sizes in both right and left hand. (X-Small, Small, Medium, Large, X-Large)

Need help choosing a size? No problem!
Example: You like the 8 lb ball but the holes are too small. The 12 lb ball fits good but it's too heavy. The answer would be to purchase an 8 lb ball with Medium Standard Drilling. It's that simple!

Roto Grip wants everyone to be a winner that is why they are introducing the Roto Grip Winner bowling ball. This ball takes the original Hotshot core and modifies it to decrease the RG and increase the differential in order to create more downlane reaction. This core is paired with the VTC-P18 Pearl reactive coverstock which maintains the balls traction all the way down the lane while storing energy for the backend. Out of the box this ball was designed to win on medium oil lanes.
