wherein the composite face insert comprises a corresponding geometry to receive the internal hosel surface, and
wherein the corresponding geometry of the composite face insert comprises a notch proximate to the heel portion of the composite face.
8. A golf club head comprising:
a golf club body having a face, a crown and a sole together defining an interior cavity, the golf club body including a heel and a toe portion and having an x, y and z axes which are orthogonal to each other having their origin at USGA center face,
wherein the golf club body has a volume between about 100 cm 3 and about 500 cm 3 ,
wherein at least one of the sole or the crown is at least in part a composite material,
wherein the golf club head has a primary alignment feature comprising a line delineating a transition between at least a portion of the golf club body having an area of contrasting shade or color with a shade or color of the face,
wherein the primary alignment feature is tooled into the golf club head with the face of the golf club body,
wherein the face of the golf club body comprises a composite face insert and the golf club body comprises a recessed face opening configured to receive the composite face insert,
wherein a portion of an internal hosel surface intrudes into the recessed face opening,
wherein the composite face insert comprises a corresponding geometry to receive the internal hosel surface, and
wherein the corresponding geometry of the composite face insert comprises a thinned portion proximate to the heel portion of the composite face.
9. The golf club head of claim 8 , wherein the face is at least in part a composite material.
10. The golf club head of claim 9 , wherein the primary alignment feature is hard tooled into the golf club head by bonding the face to the golf club head.
11. The golf club head of claim 8 , wherein the golf club head has a secondary alignment feature comprising a line delineating a transition between a first portion of the crown and a second portion of the crown,
wherein the secondary alignment feature is hard tooled with a crown insert of the golf club body.
12. A golf club head comprising:
a golf club body having a face, a crown and a sole together defining an interior cavity, the golf club body including a heel and a toe portion and having an x, y and z axes which are orthogonal to each other having their origin at USGA center face,
wherein the golf club body has a volume between about 370 cm 3 and about 500 cm 3 ,
wherein the golf club body has a body height defined from a bottom most portion of the golf club body to a top most portion of the crown of no less than 48 mm,
wherein the golf club body has a body length defined from a leading edge of the golf club body to a rearward most portion of the golf club head of no less than 98 mm,
wherein the face and the crown are at least in part a composite material,
