- Weight block inside the ball
- Core Type
- Basic shape type of the core (Symmetric, Asymmetrical, Pancake)
- Radius of Gyration: measurement related to weight distribution of the core. This affects how quickly a ball will get in to a roll. A ball with a higher RG will roll later. A ball with lower RG will roll sooner.
- 16 LB. - 2.488
- 15 LB. - 2.475
- 14 LB. - 2.492
- 13 LB. - 2.597
- 12 LB. - 2.593
- Difference between the RG of the core's x-axis and y-axis. Indicates track flare potential and stability. A higher differential means more flare potential and less stabilty. A low differential ball will be more stable and have less flare potential.

- Intermediate Differential
- Difference between the RG of the core's x-axis and Z-axis on an asymmetrical core. Indicates the asymmetry of the core. A higher intermediate differential ball will be less stable and will transition more quickly from skid to roll than a ball with lower intermediate differential.
- Providing an ideal blend!
The Strata provides the ideal blend of strong mid lane with continuous backend. To get the desired performance, the Track design team started with the new Strata core, and the strongest Q.R. cover to date, QR-11 Solid.
- Durability Optimization Technology
The Strata uses patent-pending Durability Optimization Technology (DOT) which represents a revolutionary change in the way bowling balls are manufactured. Developed by Brunswick engineers with one goal in mind – to significantly reduce cracking in performance bowling balls.
- DynamiCore Technology
The Strata uses DynamiCore – the industry leading innovation in outer core technology developed by Brunswick Bowling Products. This leap in bowling ball technology is a more durable outer material that yields less compression upon impact increasing hitting power and creating an undeniable difference in sound and pin carry.
