1. A golf club head comprising:
(i) a bore having a center that defines a shaft axis which intersects with a horizontal ground plane to define an origin point and a vertical shaft axis plane, wherein the bore is located at a heel side of the golf club head, and wherein a toe side of the golf club head is located opposite of the heel side;
(ii) a face positioned at a front portion of the golf club head where the golf club head impacts a golf ball, opposite a rear portion of the golf club head, wherein the face has an engineered impact point, a top edge height, a lower edge height, a blade length measured horizontally from the origin point toward the toe side of the golf club head to the most distant point on the golf club head in this direction, wherein the blade length includes a heel blade length section measured in the same direction as the blade length from the origin point to the engineered impact point, and a toe blade length section, wherein the heel blade length is at least 0.8″;
(iii) a sole positioned at a bottom portion of the golf club head;
(iv) a crown positioned at a top portion of the golf club head, whereby the face, the sole, and the crown define an outer shell;
(v) a center of gravity located:
(a) vertically toward the crown of the golf club head from the origin point a distance Ycg;
(b) horizontally from the origin point toward the toe side of the golf club head a distance Xcg that is generally parallel to the face and the ground plane; and
(c) a distance Zcg from the origin toward the rear portion in a direction generally orthogonal to the vertical direction used to measure Ycg and generally orthogonal to the horizontal direction used to measure Xcg;
(vi) a club moment arm from the CG to the engineered impact point;
(vii) a shaft connection system socket extending from the bottom portion of the golf club head into the interior of the outer shell toward the top portion of the club head and having a socket depth and a socket wall thickness, wherein the shaft connection system socket has at least a distinct socket toe wall and a distinct socket fore-wall, angled with respect to one another, and a socket crown-most point at an elevation less than a Yeip distance measuring the vertical elevation of the engineered impact point above the horizontal ground plane; and
(viii) wherein the golf club head has a characteristic time of at least 240 microseconds.
