The profile of the shaft of the cue as it as it increases in diameter from the tip to the joint. A "fast" or "slow" taper refers to how quickly the diameter increases. A "pro" taper describes a shaft that tapers rapidly from the joint size to the tip size so as to provide a long, untapered stroking area.
