Perfect Scale:  223.7

Breakpoint Shape:  Skid/Flip

Personal Ball Reaction:  Strong Backend ball good for playing straight or opening up angles.  Responds to friction well making it slightly more forgiving to speed and hand position. Prefers oil at least in the heads.   Continues strong through the pins.  More of a strong arc than a skid flip reaction but this could be a result of games on ball.

Perfect Scale:  154.3

Breakpoint Shape:  Length w/ Strong Backend 

Personal Ball Reaction:  Slow backend, difficult to carry with before resurfacing.  Sensitive to friction, speed and hand position.   After resurfacing this ball has become much more controlled and extremely heavy rolling.   Better for playing straighter angles and susceptible to carry down causing moves to the right.   If kept in head oil the ball will tend to not over react an stay very repetitive and controllable.
