14 LB. - 2.50
15 LB. - 2.48
16 LB. - 2.48
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. - .053
15 LB. - .056
16 LB. - .048
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.
