Fluted Feel ShaftA newly engineered putter shaft with a softer section located 5" from the tip, intently designed to enhance feel, increase stability and tighten dispersionWhite True PathThe science of white. White is the most reflective color, which allows the human eye to clearly see the path of the stroke and the ball. The new white ball design shape allows golfers to use the front of the face for alignment and the two rails/dots to center the golf ballNew Multi-Material DesignThe use of a combination of multi-materials like heavy tungsten in the back weights creates a deep CG for better distance control. Lightweight aluminum and composite create better performance advantages around the circumference of the head. Heavy steel is strategically co-molded on the frame of the heel and toe areas for optimal stabilityCo-Molded Pure Roll 2 InsertThe first co-molded insert manufactured of white TPU urethane with silver aluminum beams at a 45* angle designed to produce better roll and feel characteristicsThree Dot AlignmentThree dots form a distinguishable pattern that's easily tracked by the eye, aiding in both the alignment and path while delivering a premium aestheticHead ShapeSlightly more streamlined head design that features "softer" lines and a more rounded backside. Spider EX head size is a little larger 3.5 mm (heel to toe) and 2.7mm (front to back) than Spider XTungsten Back Weight20g, 25g, and 30g tungsten back weights (2 per head) support the deep CG and stabilitySteel Side Weights28g (2 per frame/56g) of steel is strategically placed around the circumference of the lightweight frame for increased MOI
