Kinetic Pearl

Outer shell of the ball
UMP Gen 2 Pearl
Surface texture on the ball (sanded, polished, etc)
Lane Condition
Length and/or amount of oil on the lane
Medium to Heavy
Color of the ball
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. - 2.46
15 LB. - 2.46
16 LB. - 2.49
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.
