McDermott Cue recently introduced a new more affordable line of performance shafts called G-Core Shafts. They are a good quality shaft with some impressive technology. They are a solid maple shaft, except for the tip end of the cue. From the tip and 8 inches back the cue has a multilayer construction that includes a layer of carbon fiber. The result is a unique cue that is 1 solid piece of wood and still provides more predictable deflection and cue ball squirt. This is usually referred to as radial consistency. These cues also are available in different shaft diameters between 12mm and 14mm. A big plus that the other performance shafts do not offer.
