- 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.
- 14 LB. - 2.53
- 15 LB. - 2.52
- 16 LB. - 2.56
- 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.
- 14 LB. - .045
- 15 LB. - .052
- 16 LB. - .046
- 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.

- Manufacturer's Intent
The 715C was designed to be a stronger version of the popular 505C. The designers set out to make a more aggressive product without compromising on the continuous/control factor at the breakpoint. We are
introducing an all “NEW” coverstock for this ball, the “UMP GEN 4C” with pearl essence, which boasts a greater surface texture. The pearl essence has no performance benefit; it is purely to enhance the look of the product. The “Catback” core is still a 0.015 intermediate differential, which gives this ball unbelievable striking power. The Black/Red/Gold combination will have great shelf appeal, at 2000 grit Abralon® sanded and beautifully polished with Powerhouse Factory Finish. Each new ball from Track will include a microfiber cleaning pouch with instructions on its use to help our customers maintain their performance products.
