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.

Spin is the amount of ball rotation generated by the rubber. This is affected by the rubber's tackiness, sponge thickness, sponge hardness as well as the blade's flexibility.

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.

Deception refers to the ability to produce funky balls whose spin is hard to read. Deception may refer to randomized spin or wobbling knuckle balls.
