Product details:

In the HP Series, an additional 60 grams is placed in the grip end of the club to counter the heavier putter head. Counter-balance technology increases the club's moment of inertia (MOI) for stability throughout the stroke. There are two distinct head designs in the HP series putters a traditional anser-style design and an oversized mallet style. Each head features an easy-alignment design that makes setting up accurately easier than ever before. HP Series counter-balanced putters are available in two lengths - 36 and 38 to allow the additional 60 grams of weight to be positioned above the hands of the golfer.
