I have a Taylormade RBZ driver, just recently something has started to rattle about inside the head. Does anyone know what this can be and will it affect the shot?
As already posted its likely to be glue...no need for concern as i5 won't impact on strength or playing charecteristics (but it can be a bit annoying!)
I've got the same thing with my 7 iron - which I can't be bothered to remove the grip to empty out and replace. So I know how annoying it can be!
I agree with the other prognosis. If you can't get the shaft off and the rattling annoys you (or a pro) can take the grip off and potentially get it out that way (and probably a good time to regrip)
