Golf club head with optimized characteristics and related method

Abstract

Golf club heads often possess a variety of characteristics, and these characteristics frequently interact with each other. Therefore, adjusting or setting one characteristic may fundamentally alter another, often resulting in a disadvantage. [Solution] Embodiments of golf club heads having optimized characteristics, including optimizing the head center of gravity height and depth with respect to head volume and mass, are presented herein. Other examples and related methods are also disclosed herein.
