         6 . The golf club head of  claim 1 , wherein the first axis is substantially parallel to a toe-heel direction of the golf club head, and the second axis is substantially perpendicular to the first axis. 
     
     
         7 . The golf club head of  claim 1 , wherein the golf club head further comprises a cover adapted to releasably secure the weight within the weight chamber. 
     
     
         8 . A golf club head comprising:
 a striking face having a lower leading edge and an opposite upper topline edge;   a sole extending rearward from the lower leading edge, wherein the striking face and the sole form at least part of an outer surface of the golf club head;   a weight chamber formed in the outer surface;   a weight comprising a heavy portion and a light portion, and being positionable in the weight chamber with:
 a first orientation; 
 a second orientation that is rotated from the first orientation about a first axis; and 
 a third orientation different from the second orientation and that is rotated from the first orientation about the first axis. 
   
     
     
         9 . The golf club head of  claim 8 , wherein a center of gravity of the weight is offset from the first axis. 
     
     
         10 . The golf club head of  claim 8 , wherein the first axis is substantially parallel to a toe-heel direction of the golf club head. 
     
     
         11 . The golf club head of  claim 8 , wherein the weight is configured such that:
 when the weight has the first orientation, the heavy portion is proximal to the sole;   when the weight has the second orientation, the heavy portion is distal to the sole; and   when the weight has the third orientation, the heavy portion is proximal to the striking face.   
     
     
         12 . The golf club head of  claim 8 , wherein the light portion has a plurality of long sides, each being elongated along an elongation direction, and is shaped and sized such that, when the weight is positioned in the weight chamber, the elongation direction is substantially parallel to the first axis, and
 wherein the heavy portion is coupled to at least one of the plurality of long sides of the light portion.   
     
     
         13 . The golf club head of  claim 8 , wherein the weight chamber is at least partially in the sole. 
     
     
         14 . A metalwood golf club head comprising:
 a body comprising:
 a striking face having a lower leading edge and an opposite upper topline edge, 
 a sole extending rearward from the lower leading edge, and 
 a crown coupled between the sole and the upper topline edge, wherein the striking face, the sole, and the crown form at least part of an outer surface of the body; 
   a weight chamber formed in the outer surface; and   a weight comprising a heavy portion and a light portion, being positionable in the weight chamber with a first orientation, and being positionable in the weight chamber with a second orientation that is rotated from the first orientation about a first axis, wherein a center of gravity of the weight is offset from the first axis when the weight is positioned in the weight chamber.   
     
     
         15 . The metalwood golf club head of  claim 14 , wherein the first axis is substantially parallel to a toe-heel direction of the metalwood golf club head, and the second orientation is rotated by 90 degrees from the first orientation about the first axis. 
     
     
         16 . The metalwood golf club head of  claim 14 , further comprising a cover adapted to cover at least part of the weight chamber, and a fastener configured to couple the cover to the golf club head and to only indirectly secure the weight within the weight chamber via the cover. 
     
     
         17 . The metalwood golf club head of  claim 14 , further comprising a cover adapted to releasably secure the weight within the weight chamber, and having a window configured to visibly expose at least part of the weight within the weight chamber, and
 wherein the weight has:
 a first orientation indicator positioned on the weight such that the first orientation indicator is visibly exposed through the window when the weight has the first orientation and the cover secures the weight within the weight chamber; and 
 a second orientation indicator positioned on the weight such that the second orientation indicator is visibly exposed through the window when the weight has the second orientation and the cover secures the weight within the weight chamber. 
   
     
     
         18 . The metalwood golf club head of  claim 14 , wherein the weight chamber is positioned at least partially in the sole. 
     
     
         19 . The metalwood golf club head of  claim 14 , wherein the heavy portion is coupled to the light portion via a fastener.
