The more the pellet is filled, the more the racket is rigid. A stiff racquet provides more power while a flexible racquet provides more feel.

The more the pellet is filled, the heavier the racket. A heavy racquet provides more stability while a light racquet provides more maneuverability.

The more the pellet is filled, the more the balance is towards the head. A balance toward the head provides more power and a balance toward the shaft provides more speed.

The more the pad is filled, the more powerful the racket.
