I have a set of Ping Eye2's that are in good shape, with the original steel shafts. I cannot tell what flex they are, but I think stiff. I like the irons, but need more distance and have been thinking of a new set. My question, would I benefit by reshafting my Pings with some good graphite regular flex shafts, or should I sell them and custom make Snake eyes or Dynagolf etc. My swing speed with a 6 iron is about 75 and I hit it about 140 yards . Handicap is 25 or so.
