I bought a 909F3 13* this past season.  I noticed a slight rattle about halfway through the season and shrugged it off thinking it was simply apoxy.  Now there is a significant rattle inside the club head when it is dropped on the turf and you do not hold the grip tight.  It sounds very metallic like an internal weight or something.  Is there any way I can get this fixed/looked at/ what is it!?!?

Thank you.
