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)

Below are five examples of typical hole sizes you will find in house balls at the local bowling alley.

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!

The Roto Grip Idol Pro uses the Ikon core that changed the perception of the HP3 line for Roto Grip. This core has a low RG symmetrical shape with high differential that generates flare as well as awesome motion down the lane and on through the pin deck. The Idol Pro introduces the eTrax-S19 Solid Reactive coverstock which was designed to offer more traction on oil without reacting too early. This cover is finished with a 3000 grit Sheen. The solid coverstock with a sheen finish allows this ball to get through the front of the lane with a controlled reaction at the breakpoint on medium to medium/heavy oil conditions.
