Predator 314-3 5/16 x 14 Black Collar pool cue shaft is the all-around athlete. Stiffer than a Z-3, but not as stiff as Vantage, the preferred taper and diameter of countless champions are even more accurate than before. With the addition of V-Tek construction, the 314-3 is 3% lighter than the 314-2 at the front end and even stronger than before.
