RG
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.

15 LB. - 2.52
16 LB. - 2.56
Differential
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.

715T Product Notes

Description

Track’s 715T is the first “T” (Track-tion) ball released in the 7 series; designed to be a stronger version of the popular 505T. The designers set out to make a more aggressive product by using an all new UMP GEN4T coverstock. This cover has a larger footprint on the lane to help carve through the head oil. The “Catback” core was unchanged and is still a 0.015 intermediate differential, which gives this ball unbelievable striking power.
