1. A high volume aerodynamic golf club head (100) comprising:
A) a body (110) having a club head volume of at least 400 cc, a face (200), a sole section (300), a crown section (400) having a fiber composite material crown portion, a front (112), a back (114), a heel (116), a toe (118), and a center of gravity (CG), wherein the body (110) has a front-to-back dimension (FB) of at least 4.4 inches;
B) the face (200) having a top edge (210) and a lower edge (220), wherein a top edge height (TEH) is the elevation of the top edge (210) above a ground plane (GP), and a lower edge height (LEH) is the elevation of the lower edge (220) above the ground plane (GP), wherein a maximum top edge height (TEH) is at least 2 inches; and
C) the fiber composite material crown portion having a crown apex (410) located an apex height (AH) above a ground plane (GP), wherein:
(i) within a front-to-back vertical section through the crown apex (410) and perpendicular to a vertical plane created by a shaft axis (SA), a portion of the crown section (400) between the crown apex (410) and the face (200) has an apex-to-front radius of curvature (Ra-f);
(ii) within a heel-to-toe vertical section parallel to the vertical plane created by the shaft axis (SA), a portion of the crown section (400), above the elevation of the maximum top edge height (TEH), has a heel-to-toe radius of curvature (Rh-t), and the heel-to-toe radius of curvature (Rh-t) in contact with the crown apex (410) is less than 4 inches;
(iii) within the front-to-back vertical section a portion of the crown section (400), above the elevation of the maximum top edge height (TEH), between the crown apex (410) and the back (114) has an apex-to-rear radius of curvature (Ra-r);
(iv) wherein the apex-to-front radius of curvature (Ra-f) at the crown apex (410) is at least 25% less than the greatest apex-to-rear radius of curvature (Ra-r) of the portion of the fiber composite material crown portion within the front-to-back vertical section;
(v) the crown apex (410) is behind the forwardmost point on the face (200) a crown apex setback dimension (412), and the crown apex setback dimension (412) is less than a CG depth distance that is parallel to the crown apex setback dimension (412) and measured from a vertical projection of the center of gravity (CG) on the ground plane (GP) to a vertical projection of the forwardmost point on the face (200) on the ground plane (GP); and
(vi) the crown apex (410) is located between the toe (118) and a vertical front-to-back plane through the center of gravity (CG);
D) the high volume aerodynamic golf club head (100) has:
(i) a first moment of inertia (MOIy) about a vertical axis through a center of gravity (CG) of the high volume aerodynamic golf club head (100) that is at least 4000 g*cm2; and
(ii) a second moment of inertia (MOIx) about a horizontal axis through the center of gravity (CG) that is at least 2000 g*cm2.
