The G-Core and i-Shaft utilize McDermott's proprietary triple-layer carbon fiber core technology to create the most radial consistent shafts on the market. Radial consistency is the ability to reproduce the same results regardless of the shaft's orientation. This means the shaft will perform the same way on every shot. McDermott's high-performance shafts consistently provide a straighter cue ball path, minimizing the need to compensate for spin and throw. The carbon fiber core's stability combined with McDermott's tri-core butt construction gives every cue a solid, consistent feel known throughout the industry as the "McDermott Hit."
