Improved golf club heads indicating the location of an optimum hit point on the striking face for maximum shot distance of any hit location on the face ("maximum distance spot", called MD) and an indication of a second optimum hit point giving best distance, with the condition of minimum or no change of torque caused feel as perceived by the golfer at impact ("best feel spot," called BF) are disclosed. Methods to locate these optimum locations are described. It has been widely assumed and believed that these two points have the same location. The present inventors have found that this is not true. The principal application is to "wood" type golf clubs designed to hit golf balls from a tee, but can provide useful information for clubs hitting balls from the ground. The indication of MD and BF locations on the club face may take any of various forms.
