Sometimes the best way to redistribute mass is to take it all away, replacing it completely with air. That’s the technological story here because the middle of these putters is cut away entirely. This optimises stability for the highest moment of inertia of any Spider putter. The first step in the process is the light-aluminium body, one that uses less mass so that the perimeter is heavier for better balance. Heavier steel weights are positioned at the club’s edges, pushing about a third of the weight to the perimeter. The back bar of the SR model even houses a separate tungsten weight to double down on stability. The face insert has grooves angled at 45 degrees for a smooth roll and distance control, and the white alignment section frames the ball and the path before the stroke is started.
SPECS 2 models (2 hosels); head weight 350-378 grams; length 33-35 inches
“The weight and feel of the putter are top-notch. The alignment markings are like a runway. The rollout seems automatic.”
