Abstract
The invention provides golf club heads having aerodynamic features that disrupt air flow over the face when the club is swung. The features are milled into the face of the club head, including curved faces found in wood-type club heads. During a swing, the features cause the boundary layer to separate at a point closer to the rear of the club head during a swing, resulting in reduced drag. The invention also provides golf club heads with faces having a central region of symmetrical surface roughness. The symmetrical roughness in the central region of the face of wood-type club heads allows for shots with less spin and greater distance.
