During the summer i had a couple of custom fitting sessions up at St Ives,
I was fit for titleist through the bag. With the release of the 913 D2's, F's
and H's upon us. Using the results of said fitting, still using the same type,
make, flex of shafts and the same numbers from the performance guide
i.e. A1. Can i just make a straight swop or do you advise a re-fit?
