Match putter arc and toe hang to your face rotation
Ping sorts putters into three arc categories based on how much the face rotates during the stroke. A straighter, more face-balanced putter is designed for roughly zero to three and a half degrees of rotation; a slight-arc putter fits about three and a half to seven and a half degrees; and a putter with more toe hang is for a player with a lot of face rotation.
