UST Mamiya engineers have created a new higher performance Proforce. PROFORCE V2 is ideal for golfers seeking a flatter trajectory. PROFORCE V2 uses aerospace grade materials and innovative design to produce a very stable and consistent golf shaft. The low torque provides maximum control for today's larger club heads and provides significantly improved lateral stability. Thereby, delivering increased energy to the golf ball at impact, and a more consistent release path swing after swing.
