Key Technologies & Design
Ai-DUAL Insert
-
New AI-engineered dual-layer urethane insert with a soft outer layer and firmer inner core for consistent ball speeds and improved forward roll across the face.
Square 2 Square (“S2S”) Zero-Torque Balance
-
The centre-shafted hosel sits directly beneath the club’s center of gravity, creating a zero-torque balance that helps keep the putter face square through the stroke — ideal for straight-back, straight-through styles.
Forward Roll Design (FRD) Grooves
-
Deeper, steeper grooves (~19° slope) promote rapid forward roll and reduce skid immediately after impact for more reliable distance control.
Built-In Forward Press & Reverse Taper Grip
-
Many S2S models include around 2° of built-in forward shaft lean that presets the hands in a stable forward press, helping prevent the face from opening at impact, while the reverse-taper grip aligns the grip’s leading edge parallel to the putter’s leading edge for a natural setup feel.
