The Tour AD DI also utilizes premium, aerospace quality 50t carbon-fiber materials to provide the best performing shaft available. The softer mid-section bend profile of the Tour AD DI allows the player to load the shaft properly, yet it maintains a firm enough tip section through IMPACT promoting a high launch and low spin ball flight condition. The result, the Tour AD DI delivers players to the next level in shaft performance and will create a “DEEP IMPACT” on your game!
