Predator 314-3 Uni-Loc thin black collar pool cue shaft is the number one choice for top players around the world. It is stiffer than a Z3, but not as stiff as Vantage. The pro taper and 12.75 mm diameter is even more accurate than before. With Predators addition of V-Tek construction, the 314-3 is 3% lighter than the 314-2 at the front-end and even stronger!
