The Red series is designed for the harder-hitting golfers to provide additional control. Heavier weight and/or increased stiffness help to provide incredible stability for golfers that may have faster swing speeds or quicker and more aggressive tempos. Four distinct shafts in the series start with a stiffer-tipped, ultra-lightweight driver shaft. The fairway, hybrid and iron shafts all are heavier counterparts possessing the same stiffer tip section for greater control and a slightly lower launch conditions.
