While DART technology optimizes 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. Additionally, Dual Action Recoil Technology® eliminates inconsistent areas in the golf shaft for precise feel without the ‘clunky dead feel’ of other iron shafts.
