Highly worthwhile to make sure you are playing the correct shaft and club for your swing.
Went to get fit for single length irons by Edel and found out the single length iron set I had been using was the best set-up for me. Jim only needed to tweak the specs on each iron by remaking them with my components. He did help me find a better driver and a much better 3 wood then my current ones (+15 yards with the driver and able to hit the 3wood off the deck). The Sam putt lab helped tweak my putter set-up also. It was a great and informative 3hrs and well worth the time and money.
