Designed for the Control player who wants greenside workability and spin but still prefers soft feel and low driver spin Distance off the tee combined with a favorable soft feel around the green gives DUO the "performance double-take" mantra DUO Spin is associated with the "triple-take" due to a third benefit: enhanced spin for more control on shorter shots into the green Adding an inner mantle increases spin on mid- and short-iron shots and increased resilience for ball velocity and distance The Ionomer cover generates high-lift characteristics on tee shots and long approaches from the fairway
