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.
House ball fitting examples.
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 suggestions above do not guarantee a perfect fit. It is just a simplified way of getting you a good fitting ball that you can go out have some fun with.

Out maneuver your competition with the 900Global Tactical Ops bowling ball. The S72 Pearl coverstock offers the most length in 900Globals Prefferred Line. This coverstock is paired with the Break Asymmetric core which has a higher RG which allows the cover to store more energy. The Tactical Ops core and coverstock combination generates a significant skid/flip reaction on medium to heavy oiled lanes.
