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.

The Track Alias high performance bowling ball was designed with all bowling styles and all lane patterns considered. This ball can be drilled for any circumstance you might find yourself facing. This ball can be transformed for a smooth, strong mid lane delivery or an angular motion. This is all achieved due to the versatile Alias core that is being introduced with this ball. Track designed this core to have an extremely tight pin distance and top weight spec. This will allow the driller to accomplish multiple mass bias drilling angles without the need of a weight hole. This also creates an intermediate differential range of perfectly symmetric .000 Intermediate Differential to a very asymmetric, high Intermediate Differential. This unique core is covered with a Prime Hybrid coverstock and is finished with a 500/2000 sanding. This cover responds quickly to friction on those heavier oiled lane conditions and provides a lot of hook.
