VMC Putter features the patented Variable Mass Cavity Design. Precison cast, high-strength 6061 aluminum contstruction head. Three interchangeable brass weight cartridges (50g, 68g, 86g) allow the player to adjust the head weight from 360g to 378g, or 396g to instantly adjust feel for various green speeds and personal preferences. Deep half-moon dead design allows weight to be moved from the middle of the head to the perimeter, increasing the MOI for greater forgiveness on off-center hits. Rear weighting promotes a consistent, true roll. Triple bend shaft for a clear view of the ball and face balanced for greater stability. Centered and perpendicular sight line makes it easy to align and keep the putter square. Dual aluminum-polymer face provides the ultimate combination of accuracy, feel, and distance control. DualTac Grip combines responsive feel with optimum tackiness.
