5/16 x 18 Black Collar Jacoby Ultra Pro Shaft 12.75mm – This shaft will fit standard 18 thread joints and Viking QR joints.

Reducing Cue Ball Squirt:
Cue ball squirt is caused when the cue ball is hit off its centerline when applying English.   As a result, your aiming point changes in order to compensate.   The need to compensate is minimized by reducing front weight and increasing shaft flex, so upon contact, the cue ball is able to push the shaft out of its path in order for the cue ball to stay on the desired path.

Accuracy:
The typical unwanted shaft vibration present when extreme English is applied is virtually eliminated by the vibration-dampening core. This leads to being much more accurate.

Weight:
A feather-light ferrule and vibration-dampening core greatly reduce unwanted weight in the front end.   This drastically reduces unwanted shaft deflection.

Ferrule:
Our ferrules are comprised of  hydex 202  which is very light and provides great impact resistance.   They are machined with a unique hole pattern to further reduce weight and ensure maximum tip adhesion.

Construction:
140  precisely machined individual veneers compose the shaft.   The veneers are stacked on edge, 90 degrees to the centerline. The shaft has a 18-20 inch taper

Balanced Construction:
The spliced laminated construction yields unprecedented symmetry and balance found in no other shaft, providing maximum stability and radial consistency in play.

Consistency:
Because  of the construction of the shaft, the individual characteristics of  the veneers average themselves out.   This yields a shaft that is more consistent than any other shaft in the way the shaft will react on each shot, along with the  weight and playability  of one shaft to another.
