One of the best cue producer is Exceed. They're also the same producer of mezz cues.
An exclusive for EXCEED Cues, the Power Core is a butt construction focused on creating the highest level of functionality, durability and design. The Cross Power Core method is used for Irish linen or leather wraps whereas the Dual Power Core method is utilized for wood grips.
Basics of the Power Core technology
The Power Core method encloses a solid one-piece rod from the joint to the butt end as the core with the forearm, grip and butt sleeve. This technology enables wood warp resistance and adds more strength to the butt as well as creates a solid hitting feeling.
The EX Pro Shaft, designed as an exclusive feature for EXCEED Cues, is embedded with a 470mm (18.5inch) two-step carbon fiber rod at the bottom end delivering enhanced power and equalized stiffness of the shaft. The new EX Front-end Technology generates a natural feel similar to a conventional shaft with lower deflection. The Zan Plus S as the standard cue tip combined with the original EX-Pro taper creates more cue ball action.
EX Front End Technology
The newly developed front end construction consists of three layers; the NX ferrule, maple wood and carbon pipe. Additionally, 15cm (5.9inch) of the front end core is comprised of maple and light weight foam. This ingenious design promotes “less deflection” at the moment of impact with the cue ball and the shaft enabling more power, spin accuracy and control.
