Every model features the next generation of True Roll Technology grooves that provide forgiveness by normalizing ball speeds across the face. They vary in depth and width from the center of the face to significantly improve ball-speed consistency and accuracy on putts of any length.
Weight differentiation in the high-MOI Ketsch model is achieved with different 17-4 stainless steel sole plates (355g and 388g) that vary in thickness. The putter head and TR grooves are precision milled at PING. A contrasting sight line ensures easy alignment.
