X-20 Tour are great clubs, I would suggest to get fit mostly to get the right shaft. You'ld be suprised how much a difference there is between a 5.0 and a 5.5 shaft (or 6.0), and how it affects ball filght.
If you are a low handicap (<6) and like the feel of forged, try the X-tour forged before your purchase. They are definitely not as forgiving as the X-20.
