Predator Z-3 Partial (No Joint) high performance pool cue shaft. The Predator Z-3 high performance cue shaft is lean, mean and has the most flex of all Predator Shafts. Its smaller diameter  paired with V-Tek construction allows for an extremely light  front-end and pin-point tip placement. The all-new Predator Z-3 is also 4% lighter  at the front-end than the previous generation shaft and is considerably stronger.
