A lightweight head in 6061 aluminium is combined with double tungsten weights on the outside (toe-heel) for stability, forgiveness and distance control. For the first time, two tungsten stability bars (total 172 grammes) are strategically placed at the back and sides of the putter for maximum forgiveness and optimal stability. The new, firmer multi-material Pureroll2 insert made from black TPU urethane and silver aluminium at a 45° angle is designed for better top spin across the entire face. A newly developed and very stable Fluted Feel™ putter shaft has a softer section 25 centimetres from the head, which gives better feel, increases stability and reduces dispersal.
