UST Mamiya LIN-Q RED EX Driver Shaft 6S Callaway Sleeve, 45.5 inches Elite Grips 350XT, almost new Spine aligned Mid-kick point for a strong trajectory with moderate spin. "Thick impact" and "stability" allow you to swing hard! Swing through! Five key points of LIN-Q (Link) RED EX to maximize flight: 1. Creates a solid "stable hold" essential for distance, with a smooth and flexible transition from the top. 2. Eliminates lateral wobble from the downswing to impact, achieving a stable impact. 3. High rigidity at the tip allows for a strong "pushing" impact. Amplifies energy and increases distance! 4. Follow-through also improves the direction of the ball without wobbling. 5. The overall feel (impact feel) of the shaft is good, with a pleasant aftertaste. Sold as is.
