- a y-axis extending vertically through a face center of the club head and a Moment of Inertia about the y-axis,
- a body comprising a heel, a toe, a topline, a sole, and a hosel;
- a back wall coupled to the body;
- a face insert formed of titanium and having a face insert mass, the face insert having a face insert thickness at the face center, the face insert being coupled to the body to form a hollow cavity between the face insert and the back wall;
- a toe weight member formed of tungsten and is coupled in a lower, toe portion of the hollow cavity and has a toe weight member mass that comprises greater than 25% of the club head mass;
