Ping CFS Iron Shaft Review

PING CFS Iron Shafts


By Russ Ryden, A Golf Digest America’s 100 Best Clubfitter

As a club fitter it is important to know what your are fitting with and the makeup of my customers existing clubs clubs. I did a reshaft of a set of Ping irons recently and had a chance to profile the pull outs. Here is what I measured:

PingCFS_S_EIDfTbFor comparison with other shafts on this site, the 6 iron butt stiffness was 12.9 lbs. Tip to butt ratio was 56%, indicating a mid launch. This is a parallel shaft with a .370 tip. That can be seen in the descending weight as the shafts get shorter. To some degree, the tip stiffness compresses through out the set. This can be seen by looking at the range of mid shaft stiffness compared to tip and butt stiffness range. This is typical in sets made from the same shaft that have the tip section shortened to create additional stiffness as the club heads in the heads get heavier.

What I have seen in measuring other sets of Ping irons was that they achieved both swing weight matches and were very close to MOI matches. I regret not having measured this set before I pulled it apart. The descending weight caused a fairly substantial change in the shafts contribution to the total MOI of the club. Perhaps this is why I have seen swing weight and MOI matched sets of Ping irons.[\resrict]

    Thanks for reviewing the CFS, not too much info on these shafts.

    I know when they came out PING said they would be true to flex. However, looking at the deflection it seems like they are about half a flex soft when compared to other “stiff” shafts.

  • Bryan

    So are you saying that by lowering the weight of the shaft, and increasing the head weight through a set from long to short irons you could achieve both a match in MOI and swing weight? That would be interesting, because I did not think you could be MOI matched if you were at the same swing weight throughout the set.

      The set of shafts is lying here and a box of heads arrive this morning for a built. It will be worth taking a look at these dry fitted to some heads. What you say is generally true. I am going to have to pull some ping sets off the rack and do some measuring.

    Russ, I have a member that just got a set of Ping Irons with the CFS Stiff shaft. He is seeing higher ball flight and has seen significant loss of distance. At 109 grams do these shafts play softer? I appreciate your thoughts.

    • DevotedGolfer

      As you well know, soft is a relative term. In their weight class I would not call them soft. My comments here are going to be based on looking at them in relationship to other shafts that I know. I do not have first hand experience with them. This review was done form a set of pullouts. What I see is shaft that will have a propensity to launch high. it this set is a weight/balance change from previous clubs, some of this loss of distance may be due to the changed swing dynamics brought on by a weigh change.
      A question you must ask, and it will take some form of launch monitor to get this answer, is how has the flight changed from the previous set. Is he now experiencing a drop and stop flight where in the past part of his distance came from roll out. I bring this up, because it happened to me earlier this week. The customer said his former clubs hit the green and rolled 10 yards further while with the new clubs, the ball was never more than 2′ from the ball mark. You probably know where that conversation went. 🙂 I told him to hit one lower club and start aiming at pins.

    These are NOT 370 parallel tip. They are indeed 355 taper tip. I’ve actually pulled these and put them in a set of Mizuno MP64’s for a customer..

    • Eric,
      I will have to take your word for that, I cannot lay my hands on them at the moment, there are a lot of shaft sets here in the shop. Based on the set profile I would have to agree with you. But seeing the descending weights, the set I had looks to be parallel.

  • Eric Davis

    May I ask your opinion – what shaft on the market by any mfg most closely mirror the mass and profile of the CFS-S. Nippon 1050 in stiff? 1150?

    • The 1050S is close. A little stiffer in the butt softer in the tip. But not to far off. Other than that the TrueTemper XP105’s are also close. I don’t have a full shaft match finder built for iron shafts like I do for driver shafts.
