  1. Hi Tom, if I cut my driver shaft at the butt to make it play 43.5 inches, how will the flex be affected. It’s a taylormade m2 driver with a graphite design ad di 6 x shaft. The driver currently is 45 inches. Thanks,

    • MEL:
      If you cut from 45 to 43.5″ AND IF YOU RESTORE THE SWINGWEIGHT TO WHAT IT WAS BEFORE THE CUT, then the effect on the shaft will be minimal to hardly noticeable. This is because the increase in stiffness that comes from cutting it shorter is then offset by the presence of more headweight to elicit a bending influence on the shaft during the swing. If you cannot or do not restore the swingweight after the cut, then the shaft will play a little stiffer but the main thing you would notice if you skipped the swingweight re adjustment would not be the shaft stiffness, but it would be a complete lack of head weight feel during the swing that most likely would cause you real problems with your tempo and timing and ability to hit the ball on center. So the bottom line is even if you have to slap 18 grams of lead tape all over the head to restore the swingweight, you better do it or else this change in length will be a disaster.

    • Hello Tom.im looking at building a driver at 43.5..Can I use a three wood shaft because it plays that length when installed in driver..How will the flex and swing weight perform.and can I put a 5 wood shaft in my three wood to play at 42.5..

    • COLIN

      In a set of woods made with the same shaft model and flex, the shaft in the driver is installed with 0 tip trim, the shaft in the 3w is installed with 1″ tip trim and the shaft in the 5 wood is installed with 2″ cut from the tip before installation. Then for all woods, after installation the shaft is cut from the grip end to achieve the desired playing length for each wood. Whenever you cut the tip of the shaft, you are increasing its stiffness. The reason shafts are tip trimmed for the 3w and 5w and not for the driver is because the 3w head is usually 10 grams heavier than the driver and the 5w head is 20 grams heavier than the driver. The 3w and 5w heads have to be heavier so that at their shorter lengths, they can end up at the same swingweight as the driver and as each other. More headweight puts more of a bending force on a shaft. So the additional tip trim done on the shafts for a 3w and 5w is done to offset this increased bending effect from the heavier headweight so in the end, all shafts feel like they are at the same stiffness.

      If you put the 3w shaft into the driver and put the 5w shaft into the 3w, two things will happen that are not necessarily good for performance. One, you will have made the driver and 3w a half a flex stiffer than they were supposed to be for a standard installation of that shaft. If you have felt in the past that your driver and 3w with their original shafts felt and swung too flexible for your swing and sense of feel, then having them both be stiffer might not be a bad thing. But if you have felt that your driver and 3w with their original shafts did not feel too flexible, then putting the 3w shaft in the driver and 5w shaft in the 3w would make both clubs play too stiff for you and your swing.

      Two, your 3w and 5w shafts have already been cut from the grip end to establish the playing length for both of these woods. The 3w is usually a lot shorter in playing length than the driver. The 5w is usually an inch shorter than the playing length of the 3w. Now it is possible in putting the 3w shaft into the driver that it could end up being not that much shorter than what the driver should be or was because most all driver heads have a greater distance from the bottom of the shaft bore to the ground than to most all 3w heads. but no question that if you put the 5w shaft into the 3w, it will end up shorter than what the 3w was before.

      Now maybe your idea of doing all this is to end up with a shorter playing driver and 3w for control improvement. If so, then the way to go about having a shorter driver and 3w is to just leave the shafts in them and cut them both shorter in length from the grip end of the shaft. Then because the shortening of length will have lowered the swingweight by 3 swt points for each half inch cut shorter, if you add weight back to the heads to restore the swingweight to what it was before the cuts, that head weight increase to get back to the original swingweight will make the shafts play to the right stiffness after they are cut shorter.

      Hope this helps,

    • Thanks Tom..I have my driver playing at 43.5 now and my 3 wood and hybrid perfect length.The reason I went to this length was to hit the middle of club all the time.and the switch has been a great help for my game.now I’m still having the odd drive that hits the toe or heel..So I experimented with lead tape in different locations on shaft.tried on driver and woods.when I put 50grams of lead tape just below bottom of grip on the shaft it felt great and everything about my swing improved.I can’t leave this tape on because it’s off-putting on the shaft.Is there any other way I can get club to play like this without tape on shaft. colin

      There are specially made counterweights that are designed to lock into the grip end of the shaft. Here is a link to show you what I mean – https://www.golfworks.com/tour-lock-pro-weights/p/TL0001/?gclid=CI7Qz9jIl9ICFcW1wAodSw0IYw . This type of counterweight also has a special cutter tool available that fits into an electric hand drill to enable you to cut a proper size hole through the end of the grip so you can drop the weight into the end of the shaft and lock it in place. Or you can remove the grips, install the weight, and re install the grips over the top of the weight if you do not wish to cut a hole through the end of the grip.

      What is unknown is whether putting a 50g counter weight in the very end of the grip results in the same performance as having 50 grams of lead tape just below the end of the grip. There would be about 10-11″ difference between where the end of the counter weight lives in the end of the shaft vs the middle of the lead tape below the grip. Therefore I would recommend you do ONE club only with the 50g counterweight to see if that gives you the same results you have now, before you go do all the clubs.


  2. I’m building a 21 degree 3 hybrid with an s2s shaft at 38.5 inches to go with a set of sterling single length irons at 37 inches. I’m trying to get a normal distance gap between the sterling 23 degree 5 iron and the 21 degree hybrid. How much of the shaft would you tip trim if building at the 38.5 inch length and adding 18 grams to the head.

    • Kourt
      The normal most widely seen length people make the 21* hybrid in our line is 39″. So for it being -1/2″ shorter, that really won’t cause the shaft to be much stiffer. A tiny bit that only a really experienced feel sensitive player could notice. So I would tip trim the S2S hybrid shaft the same amount as for normal length. Then just be sure to do a good job of fitting/choosing the right swingweight for the golfer based on his tempo/transition force and sense of feel for the headweight vs his swing tempo/timing.

  3. Tom, Thank you for that explanation. I know some shaft trimming charts have one spec for glued hosels and a slightly different spec for adapter based hosels. I suppose a 1/4″ to 1/2″ off the tip vs off the butt shouldn’t make a considerable difference. Thanks again.


  4. I have a s2s white stiff flex shaft on the way that will be installed in a Cobra adapter (ZL head). I would like the final driver length to be 44.5″. I would also like the shaft to play as true to flex as possible. How would I go about trimming the shaft for the adapter with the final length and flex in mind.

    Thank you

    • DON
      I am sorry but the only way we could tell you how much to trim in total to achieve a 44.5″ length and to make the flex play as true as possible in this Cobra head is if we had the Cobra head so we could measure its hosel length and distance from the bottom of the adapter to the ground. within our company we do design our head models so that the “true flex” of each of our shafts is achieved with the normal tip trim instructions we provide in the catalog and on our website. But because there are no standards in the industry for hosel length and bore depth and bottom of bore to ground, each other company is free to design their heads with whatever specs for these dimensions that they see fit. In trying the best I can to help, based on what I have seen in analyzing some of the companies’ driver heads with adapters, I would say that if you did the normal 0 tip trim the flex would be on spec. As to the length of the club, what all clubmakers do is once they have done their tip trim (if any is required) they then DRY FIT THE SHAFT IN THE HOSEL/ADAPTER and then measure and mark on the butt of the shaft where the desired playing length requires the cut from the butt end of the shaft to be made. Then they pull the shaft out, cut from the butt where they marked, then epoxy and build the club.


  5. Tom,

    Please confirm that the Future Pro Junior clubs are all just butt trimmed? What is your recommended length setup for juniors?

    • EDWIN
      Please send us an email at contact@wishongolf.com and request the tip trim instructions for the FUTURE PRO junior iron shafts. We have developed a trim chart that adjusts the tip trim based on the size and strength of the junior player involved. With this we also have a chart and information on what lengths we recommend per each different age group and size of juniors.


  6. Under Trim Chart D there is a note that reads: add 1″ for S2S Green A flex. Please specify exactly what that means. Thanks.

    • JASON

      The S2S Green shafts are combination flex shafts, meaning the A and AA flexes come from the same master shaft. To get the stiffer of the two flexes in the shaft which is the A flex, you have to tip trim more than what is called for to get the AA flex from the shaft. Hence the trim chart is set up to ordain first the tip trims for the AA flex. The reference note then is offered to tell clubmakers to add 1″ to these tip trims to get the A flex from the combination S2S green shafts.

      Sorry for the delay in responding. We had a few technical glitches with our website that caused the delay in responding. It is VERY difficult without seeing your son swing OR without being able to get his feedback, to know what shaft HE is going to like. Based on his swing and launch information you provided, ON PAPER the Kaili should be a shaft that is a little too flexible in the tip section. But since you say he likes that shaft, that makes it more difficult to predict what other shaft design he would like or dislike FROM A FEEL STANDPOINT. The S2S Red is a very unusual shaft design in that it departs from the traditional way that shafts are designed to increase in stiffness progression from the butt to the tip. But based on all of our testing with golfers who are good swingers with a late release, and considering that he likes the Kaili bend profile, I would think that the S2S Red R flex at this shorter length would be a contender for him. In the end, what really is always best for a good player is to find an experienced custom clubmaker who is knowledgeable in shaft fitting to work with him to determine what shaft HE likes.
