The streamlined, triangular mallet head shape is new to the 2-Ball lineup. It features complementary alignment lines to go along with the revolutionary 2-Ball design, making putts easier to line up for precision accuracy. The new White Ice Insert is our best feeling, multi-layer insert to date. Developed after extensive feedback from players on Tour, our engineers have enhanced the sound, responsiveness and consistency of the insert. Coupled with a new Dark Nickel finish for a premium look, White Ice putters combine Tour-level performance with Tour-inspired feel. White Ice Insert The multi-layer insert has been fine-tuned to enhance sound, responsiveness, resiliency and consistency. The inner core is 19 percent firmer to enhance the feel and 92 percent stiffer for better resiliency, leading to consistent distance control. The face surface has been roughened to enhance the sound at impact with softer golf balls. The rough texture also helps increase friction between the ball and the insert to promote forward roll. New Head Design The triangular mallet head shape creates a clean look at address and features alignment lines that complement the 2-Ball design.
