2. Pin-to-PAP Distance
   

3. VAL Angle (Second Angle)

   

   ? Why does the Mass Bias angle matter?

   • 
     A smaller MB angle means the ball will transition more smoothly from hook to roll, with less aggressive backend movement.

   • A larger MB angle increases the angularity and sharpness of the backend reaction.

   • Ball drillers use this angle to tailor the ball’s reaction for your style and lane conditions.
