CLASSIC MULTI-MATERIAL SHAPE Notchback is the most classically shaped member of the new Spider family. A lightweight 6061 aluminum body combines with heavy dual-tungsten weights on the outside (heel-toe) for stability, forgiveness & distance control. DUAL-TUNGSTEN WEIGHTS FOR STABILITY For the first time, we’ve implemented heavy tungsten stability bars (172g total) that strategically wrap around the back & side of the putter for optimal forgiveness & stability. PURE ROLL² INSERT FOR enhanced TOPSPIN The new firmer co-molded insert, manufactured of black TPU urethane with silver aluminum beams at a 45° angle designed to produce enhanced topspin across the face. FLUTED FEEL⢠SHAFT A newly engineered stability putter shaft with a softer section located 5” from the tip, intently designed to enhance feel, increase stability & tighten dispersion.
