Speed is the rating of the power generated by the rubber or blade. Speed can be broken down into loop speed (heavy topspin stroke) and volley speed (speed on flat contact, like a smash or volley). Using a faster blade/rubber produces faster shots which, at high speeds, reduces the amount of control.

Control refers to how easy it is to control the ball using this equipment. Equipment that is too fast or too spinny reduces control though equipment that is too slow or not spinny may also decrease control.

Plies refers to the number of layers of wood/composite material in the blade.

Materials - the types of wood and composite materials in the blade.

Weight is the mass of the equipment.
