The patented 2nd generation Predator 314 Shaft is the result of two years of research and development. It is designed to increase accuracy and reduce cue deflection for both the professional and beginner pool player. In fact, the majority of beginning or intermediate players notice an immediate improvement in their game when they use a Predator. Predator's ferrule (Pat. 5725437) and internal bore (Pat. 6162128) reduce the shafts tendency to buckle on impact and allow the cue ball to push the shaft aside instead of the shaft pushing the cue ball off line. Predator's technology makes it easier to hit what you're aiming at because it shoots straighter.
