Core Type
Basic shape type of the core (Symmetric, Asymmetrical, Pancake)
Asymmetrical
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.
14 LB. - 2.46
15 LB. - 2.46
16 LB. - 2.49
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. - .046
15 LB. - .044
16 LB. - .042
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.
