The four blade options here represent only part of PXG’s commitment to putter fitting through the Battle Ready line. Previous versions of these putters were milled out of stainless steel, but these have both stainless-steel and aluminum bodies with high-density tungsten inserts. The sole also features two adjustable weights. PXG’s designers used this mix of light and heavy mass to boost the moment of inertia of the club by 15 percent. This increased stability on off-center hits keeps the head on its intended path through the stroke. The heads are still completely milled to maximize feel, but a new pyramid-textured face pattern of varying size decreases in density farther away from the center. The purpose is to help toe and heel misses roll more like on-center strikes.
