UST Mamiya RECOIL DART Iron Shafts have been designed after years of research, testing and development to precisely optimize shaft hoop stiffness in the critical areas of the golf shaft. To achieve maximum distance, optimum hoop stiffness is designed into the energy transfer section of the shaft. In the tip section, the hoop stiffness is increased to maintain feel while also stabilizing the tip section for maximum consistency and optimum ball flight.
