White Hot XG #4. New for 2006. The latest generation of White Hot Technology used a multi-layer insert that takes feel, feedback and distance control to the next level. The multi-layer insert in the White Hot XG Series takes two materials with different properties to provide incredible feel and distance control. Discretionary weight is moved to the perimeter of the putter head for a high moment of inertia, better forgiveness and a truer roll. Textured Impact Zone enhances feel and clearly defines optimum impact area. The White Hot XG #4 is a heel-toe weighted blade putter with a V-align cavity, a slant neck hosel and a full-shaft offset.
