    Absolutely the best explanation I have seen of this. I have seen another more recent demonstration of the same issue by a well respected fitter using three driver shafts with the same weight but different flexes (X, S and R/S) and three shafts with different weights (50, 60 and 70) but the same stiff flex. They also put top priority on weight rather than flex. But the test focused on launch monitor data plus the location of the strike on the face. They discussed how it felt, and the tester mentioned how he felt the differences affected his backswing, and also the dispersion. But they did not deal with or explain the key biomechanics point that Simon makes so clear and simple of being able to simply move the club around him in balance, without having to make more or less effort or hand adjustments, Kudos and thanks.

    Great video. Absolutely fact. I started golf with the latest technology which consisted of steel driver shafts and persimmon heads. Today my driver has a 45 gram graphite shaft. I just can't swing a heavy club anymore.

      Many thanks. I remember those days as a junior starting with persimmon woods with steel shafts too - taught you to find the middle of the club!! You’re spot on about the weight though as it is a case of physically being able to move the club at speed and retain balance and control or not being able to no matter what other characteristics the shaft has.

      Not sure why I haven’t seen this video before ,,, It has irritated me that fitters check what shaft you are playing with and recommend something similar. One fitter said def light graphite and I was making 3 inch divots behind the ball. Sold the clubs in 2 weeks. Lately, went for a fitting and told the fitter let’s star heavy and work down - eureka 120gms. Superb tempo and getting great ball descent.

      Almost all iron shafts progress weight through the set however the AMT do progress weight much more aggressively. Whilst the principle seems good in practice they can get too light in long irons or too heavy in short irons and that can make consistent timing hard to achieve through the set

      Hi Jay. This particular video was about shaft weight which goes before swing weight in the fitting process. The 2 go hand in hand in that order. You are absolutely right though, swingweight is of paramount importance to ensure the optimal shaft weight swings correctly. Please also see our video about swingweight

    Thank you for an excellent vid and I 110% agree with your statement that "shaft weight is KING".
    I realised years ago that I have a weight "sweet spot" that works with my swing mechanics that allows me to deliver a square clubface. Anything heavier or lighter throws off my timing and screws up my clubface delivery. As Ian Fraser of TXG puts it "the shaft is a timing device".
    But there can be another factor at work here and that is our reaction to what a "Fitter tells us" about a particular shaft or club. I am VERY autosuggestive and I will react to what the fitter says about a shaft/club. So I prefer a Fitting where the fitter doesn't influence me and doesn't tell me anything about what I am being handed and just lets me react to what I feel
    That way my brain reacts purely to how the shaft feels rather than what I have been told that it should feel.

One time I went to buy & get fitted for irons and I was also hitting all left. The guy had no clue what he was doing. He just kept changing different clubs/shafts. At the end, I had to return the mizunos I bought with his recommended shaft and I didn't play well with those at all, and ended up buying p790s off the shelf and I am hitting em great.

      I would not advise trying to change the weight by much as the lead tape will probably come off so unless you were attempting a real fine tune it will be hard to make too much of a difference without needing to re-apply it fairly regularly

    In my case, of relatively slow speed of swing ~92 m/h, the weight of the shaft doesn't make any difference. I swing all shaft weights with the approximately same speed and achieve the same distance. It seams illogical but it is that what it is, I believe there must be a lot of some compensation involved. Actually I preferer heavier shafts that are much more consistent for me in the left , right distribution.

    • @Precision_Golf
      @Precision_Golf  6 месяцев назад

      You do find players who “normalise” their timing no matter what they swing but there will be a weight which gives the best and most natural synchronisation which will minimise variables. Ultimately whatever feels most natural and simple is likely to be the best for you!

    fantastic vid, and FWIW i've noticed the same thing in my own swing. I don't swing very fast (i'm in my 50's, i'm an avid golfer, i'm about a 3 handicap, and my driver swing is around 100-102 mph). But the sweet spot weight of a driver shaft for me is about 60-65 grams. The ultralight shafts completely throw my timing off. I eventually deduced it, through trial and error (buying various shafts is somewhat easy nowadays with the ability to change them out and eBay). It convinced me to educate myself over these sorts of things rather than trust just any fitter. Of course there's no way i'd know as much as a great fitter, but how do you ever know if you've got a guy fitting you of that caliber? In any case, great vid, and i'm definitely a new subscriber!

As long as they can explain the options, what the characteristics are and why they are being used then that should stand you in good stead!

  • @rossadamdixon

    I used to fit clubs for Ping amd Callaway and build clubs like Miuras. My clubs are all MOI matched. Swingweight is a completely idiotic measure of club weight. No engineer would understand swingweight as a measurment. Weight and more importantly MOI is the most important part of fitting but sadly ots just not understood or set up to fot at scale.

    • @Precision_Golf
      @Precision_Golf  9 месяцев назад

      You are correct, swingweight without any other context or being related to the components etc is just an arbitrary scale. MOI is a more scientific measure, however this cannot be matched through the set as the energy input by the player changes club to club so no scale is completely perfect. As long as the fitter understands what swingweight truly displays and how to apply it correctly during the fitting it can be utilised to good effect

    • @rossadamdixon
      @rossadamdixon 9 месяцев назад

      Well the point of this video is to show that weight is important. You could have a shaft 30 grams lighter SW the same at the heavier one but the golfer will say they feel different. This is because SW doesn't relate to what the golfer feels. They feel MOI.
      You say you can't match a set but my irons and wedges are matched exactly. Yes with woods, the length change is so large and the shafts weights so different that the target moi number is likely different. However, I have found that once you have a golfers target moi with a driver, if you make all other driver shaft combos measure that number, the player will in general say they like that feel.
      I'm not saying it is easy to do or practical for masses but what I am saying is the measure for what golfers feel in a golf club/ swing is MOI. Not Swing weight, not dead weight (static weight).They feel MOI. So in the perfect world, golfers should understand that MOI is what they should measure if they want to understand what they like or what they feel.

      Both have merits depending on the player - some players benefit from having extra shaft weight to drive against in transition, others benefit from a heavier head on a lighter shaft. The more aggressive the move in principle the heavier shaft will be better, the head weight is more about helping to time the strike/hand action.

Long story short, I disappeared off the scene and years later when I caught up with him he said he'd changed and was now hitting a fade. What he was actually doing was starting his swing with his chest and coming over the top thus losing his draw. Because his "guru" wasn't there (me), and rather than see a pro and get it corrected, he changed his stance to compensate and now spends most of his time pushing his tee shots. It's awful to watch and has cost him 50 yards+ from the tee.

      It is to do with the weight and with the dynamics they are putting in it allows them to develop more speed at the lighter weight. At the extreme loads they put in it can create impact dynamics that are impossible to recreate at lower speeds so there may be things they can achieve that mere mortals cannot!

      I think they just learned to use the club like a whip. A flexed shaft can store alot more kinetic energy. It's kinda like figuring out the point at which a whip cracks and breaks the sound barrier. Of course that is a loose analogy but that "crack" has to be the point of contact. A stiff shaft cannot concentrate energy like that to such a precise stage in it's range of motion. Deshambeau claims he has used clubs with a ladies flex successfully. I think with those factors you just have to throw conventional wisdom out the window and just build the muscle memory for the mechanics involved once you figure it out. These guy are not immortal, just cutting edge. They also use much larger grips. I'm sure that plays a role. @@Precision_Golf

    Weight and swing weight is king, I usually swing around 113-120 something with my play driver and fitter assume I swing fast, so he gave me an X-Stiff flex and I absolutely hate the feel of the club and shaft, it's simply doesn't feel good or confidence building to me.
    Stiff tip with huge heavy head makes me have a hard time closing and squaring the face.
    I have smoother deliver but fast swing not the type that load the shaft in a traditional way.
    I'm so used to do well with Stiff or even Regular flex shaft so I knew there are more to this than just gave a fast swinger a high kick X stiff shaft have a feel of swinging a metal pole.
    So many fitters do not put in the customer's feel, preference and feedback, they can get too obsessed in the numbers and performance on paper and screen that if the club feels garbage or make you feel tired after testing them a short time then it's not the right combination.

      You are absolutely spot on - you have to take into account HOW someone generates their speed and what feel they like and then you can tune it all together. The bad old ways of high speed needing a heavy x-stiff shaft should be behind us but sadly many fitters still go down this route.

    Do you have another video discussing the balance point of the shafts? Because when you refer to going lighter and heavier are you just specifically referring to overall weight? Because I'm assuming once you change the shaft weight that would significantly affect the swing weight correct? So in other words when you were swinging the 95 Grand one and it was sort of flipping and you were saying there's not enough wait to keep the timing correct aren't there several ways you can do that? I'm just trying to understand if someone has a high balance point or low balance point in the shaft and then the overall weight and that combination depending how the person wants to feel the club. Do you have another video describing that dynamic?

      Hi Jacob and sorry for the delayed reply. We will be doing another video on the subject soon - a 10g shaft weight change does alter swingweight by roughly 1 point.
      In this video I am talking about total weight change rather than swingweight specifically and that this rather than flex has the largest impact on your swing. Swingweight will affect how under control the club face is through impact and how consistent it can be but correct total weight determines general synchronisation between the player and club through the swing.

    I think this added more confusion than resolution. All 3 of these weighs seem heavy.
    Is it because they are on Irons? For a DRIVER with carbon shaft, what would be the "typical" 3 weights?
    You only mention feel as a criteria, could swing speed give us a clue / starting point of required weight? I swing (driver) 105mph.
    What about swing weight. Historically it was normally around D2 (Driver). Nowadays it seems more like D5. Different shaft weights certainly change that. Is that what you are, by default, actually "matching" ? If so is there a typical average / Hi / Low range of swing weight for driver at say 105mph?
    Schaun

    • @Precision_Golf
      @Precision_Golf  Год назад

      The typical three driver shaft weights would be 55g, 65g and 75g however you cannot say what weight would work for a particular swing speed when it is strong at over 100mph - you have to match the weight to his someone moves therefore minimising compensation at impact and therefore improving consistency.
      Shaft weight does change swingweight but that is not what is being matched but if forms part of what gives consistency. Low swingweight would be D0, high would be D5 but it is a wide window.
      Ultimately the video was to show shaft flex does not affect performance as much as historically and regularly said, shaft weight is what dictates the majority of consistency of contact and shot dispersion.

I should add - one time I hit with this club and found the ball 2 holes to my right 300 yards up. I still had 350 to the hole. Yes I did par the hole.

    Might be true. But there's some self fulfilling prophecy in there. There's always some bias when you know what you're dealing with. Blind test needed. And also, people adapt, so my guess would be that you would do pretty good with a lighter shaft if you used it more.
    For my two cents, bend profile is most critical. It has to bend enough to feel a slight kicking sensation, and that in a way that the club is delivered in the right angle. For driver, launch angle is critical, if too low, a low kick shaft might help (if you are not into buying a new head). And vice versa.
    Overall swingweight determines, if you feel comfortable accelerating the club. You have to feel some weight "resistance", but not so much that your muscles can't keep up.
    Beautiful swing, by the way.

    • @Precision_Golf
      @Precision_Golf  6 месяцев назад

      Many thanks. You say people adapt and they will do so if they have to, however the idea of fitting is to not need to adapt to make the club work. Bend profile makes a small difference to launch and spin and certainly to feel which can help confidence in the club.
      All elements have a relevance and influence the end result but the wrong weight and balance point will make the biggest difference to getting a consistent result.

      Hi Kevin. How you move the weight and how it synchronises with your movement patterns is the real key - the two should compliment one another and whilst swing technique will dictate shot patterns the consistency of these and the consistency of strike is aided by the club. If you are having to change your swing to find timing and solid contact then there are likely to be elements of the fitting that have not gone to plan and best to get checked out

    Interesting topic, shaft weight! To prove your point you switched to a lighter and a heavier shaft weight with the same club head. But should you have remeasured the swing weight and adjust it accordingly to your original clubs' swing weight? So the feel of the club is the same during the swing.

    • @Precision_Golf
      @Precision_Golf  7 месяцев назад

      When you change shaft weight a by-product is that swingweight changes too - just matching the swingweight would not have made them feel the same to swing and the purpose of the test was to show what solely changing that one parameter does. To match swingweight we would have had to change head weight so two parameters would have been altered, which would have then meant any performance change might not have been directly attributed to the change in shaft weight.

      @Precision_Golf  10 месяцев назад

      A heavier shaft usually has lower torque value but this will not affect the swing.

    Great video. I have a question. When you say weight of the shaft are say swing weight of the entire club (swing weight) or weight of the shaft? For instance, if I have a shaft that is 2 inches shorter it would play stiffer but the shaft itself would weight less just because there’s less material.

    • @Precision_Golf
      @Precision_Golf  9 месяцев назад

      This is the base weight of the shaft. By shortening the shaft 2 inches if off the butt end then flex will not change much but swingweight will drop by 10 points or more and shaft weight would only go down 5g of so. The shaft would feel stiffer due to the swingweight dropping and getting less feel for the head. Getting it right for a player is a case of using the dead weight to keep the body and coin moving together and the swingweight to time the release.

      Definitely do not compensate with grip weight as you will just make the swingweight heavier by doing so - 10g grip change will be a good 2 swingweight point change so each part of the club (head, shaft and grip) must be treated individually when assessing the weight and balance of the club rather than as a collective.

      There is a minimum effective weight just as there is a maximum effective weight. Go too light and there is not enough mass to build speed with and you lose control and strike and will not hit many fairways! Swingweight can never compensate for too much or too little shaft weight and there is an optimum weight for everyone. Lighter in theory might mean more speed but in practice it can reduce it because the club does not stay in plane and therefore the swing loses efficiency

How you move the club and develop speed dictates where you need the weight and how much time of it which in turn allows you to stay balanced in the swing and reduces compensation

    I cant reply to the last comment for some reason, but what does it mean when kbs shafts are not overly tip balanced?

      It means the balance point in the shaft is not in the tip end and more in the middle making them swing lighter than one with a balance point nearer the head

    Excellent discussion! By the way, what connector fitting system are you using? Is it All Fit? Thank you.

    This probably explains why I tend to miss my irons left and my woods and driver right. My irons shafts are AMT reds.

    I play xstiff or txstiff In irons but prefer lighter driver shaft. It is not about shaft weight it is more about preference and kick/bend profiles…
