    What is the VCOG of the 919THI drivers?

    I am interested in learning how club head designs affect the performance of the clubs. Are there any books and resources that you would suggest me to look into?



      Since you have a strong interest in this topic, it is very easy for you to find the VCOG to measure yourself. Get a 1/8″ pin punch and secure it in your bench vise vertically. Now balance the driver head on its face on top of the pin punch. It’s not hard to do that. That tells you where the CG projects forward from the inside of the head to the face. The VCOG is 2mm lower off the ground than the mark of the balance point on the face because of the loft. You see, when you balance a head on its face on top of a pin punch, the face is at 0* loft relative to the pin punch. So when the head sits on its sole and the loft now is displayed on the face, the real CG inside the head is just a little lower than its projection on the face. And if you want to know the face to back CG position you just balance the head on its sole on top of the pin punch. Good luck and have fun !!

      As to books that discuss the design elements of clubheads, I am sorry but I do not know of any such books that cover that. The reason is simply because it would be such a small audience that would ever be that interested in the topic so no publisher would commission such a book to be written. I will say that I am about 2/3’s done with writing what probably will be my last book. It will be a combination of two parts, one that shares some of the fun and interesting stories and experiences from my long career in club design and research. The other half will be a compilation in short form of as much of what I have learned about golf clubs as I can remember and pack into a short bullet point type of presentation so it gets right to the point and is not too long. In that section of the new book you will find a lot of the information you seek about head design elements and performance from a pure practical real life standpoint. I am hoping to get the book done so it can be available around Christmas of this year.

      Thanks again for your interest. And for sure if you want, send me questions you want to have the answers to and I would be glad to respond to help you.

      Thank you for your reply. I have a simple COG measuring stand from Golfmechanix and I tried to measure the VCOG of the Wishon testing heads I have. They seem to be at 20mm from the top of the crown and a little to the heel side. Really interesting to learn that the actual VCOG will be 2mm lower. The test heads have the Faz-fit connectors so I wonder if the extra weight in the hosel would have shifted the VCOG. I will test again, have a 919THI coming in tomorrow.


      If you had every company’s driver head off the shaft to do a balance on the face check of the approximate CG location you would find that pretty much the only way VCOG varies by more than a couple of mm is when you have one driver with a shorter face height vs another with a taller face height. You’ll find that the ratio of how much face is above the CG vs how much is below is virtually the same for all drivers. That comes about just because drivers are so similar in how much mass is on the upper half of the head vs the lower half. I have found over the 33 yrs I have been designing heads that VCOG on a driver is pretty much a worthless specification that means virtually nothing to performance as long as most drivers are so close to being the same size and height. Only if you go to a smaller head driver with a substantially shorter face height do you see VCOG become a lot lower in relation to the ground. But all that is still pretty much a moot point because we hit the driver with the ball perched up on a tee. Because of that even with a shorter face height driver the relationship of where the VCOG is in the head vs where the ball’s CG is at impact is pretty much the same. Only when the golfer has a more steep vs more upward angle of attack will the VCOG begin to have any real effect. And even with that, as clubhead speed drops lower such as under 90mph, slower speed players see virtually no benefit from a low CG in a head. The increased sliding effect of the ball up the face from the VCOG being a lot lower than the ball CG needs a higher ball speed to really throw the ball noticeably higher in the air.


    • Tom’s Wishons book,Common Sense Clubfitting, is an an outstanding book that explains clubhead and shaft designs and how they relate to the fitting process. That is my go to book. It should be in every golfers/clubfitters library.

    • I have read Tom’s book twice and always go back for references when something is unclear. I have read Maltby’s book, Jeff Sheet’s book, all are great but Tom’s book is the easiest to follow, the most practical out of all of them. It tells you what matters to get the best performing set of clubs, not the brouhahas that’s out there. I think everyone that is either a club fitter/builder or a golf professional in general should read this book and keep it as a reference.

  2. Hi Tom. I found your statement below very interesting. So, basically we should are you saying that we should not buy premium or upgraded shafts?

    “i keep my shaft design prices very reasonable because I believe firmly that this matter of shafts for woods costing $200, $300 is one of the, if not the single biggest scam ever put on golfers in the history of the game. Period. And anyone who tells you different does not know stuff from shinola about shafts I can assure you. “

    • BRETT:

      It is possible to find the same exact bend profile (stiffness design from butt to tip) in a $50 shaft or less that you can find in 95% of the high dollar shafts. I know this because from 2006 to 2016 we created, supported and sold our Bend Profile Software program which showed and stated the bend profile stiffness measurements of many different shafts from many different companies in numerical and graph form. With this software it was possible to select any of the 3,000 shafts we had in the data base and then have the software run a match based on how close you wanted to be to the same numerical measurements of the selected shaft. We found over time that if you found a shaft that was within 2.5 to 3% of the original’s bend profile specs, it was for all intents and purposes the same shaft in terms of performance and feel. With this search tool in the software many clubmakers were able to use it to find alternative shafts of far less cost to many, many of the high dollar shafts. And the validity of this process was proven over and over when the clubmakers re shafted or built a new club with the “alternative” shaft and the golfer and the clubmaker found it played the same.

      Unfortunately many of the high dollar shaft companies got wind of how our software could be used to find very similar shafts to theirs so many of them stopped providing us with samples of their shafts to measure to put into the data base. You see when we created this software back in 06, at that time most all the shaft companies did support the project by providing me with multiple samples of each of their shaft models and flexes so we could do the bend profile and spec measurements to put that into the Bend Profile software’s data base. This match search capability was a lesser part of the program but soon many of the clubmakers discovered how it could be used to search for similar shafts. Sadly the word of that capability just ruined the whole project because we were most definitely not in a position to go out and buy multiple samples of every shaft model in each flex just to be able to measure to put into the data base. So when many of the shaft companies stopped supporting our efforts to create an industry wide data base of empirical measurements of shaft stiffness, weight, balance point, etc, it pretty much destroyed the project. We are looking at alternative ways to get our hands on as many of the shaft companies’ shafts to re-vitalize the software but as of right now we don’t have that going. But it is on the ‘to-do’ list for the not too distant future.

      Thing is, without some repository of empirical measurements of stiffness and weight at the least, it is pretty darn hard to find shafts that have similar bend profile and specs. But with such a data base it is very easy to do that. And despite the fact this use of the search function in our former software project did prove to be the nail in the coffin for keeping that data base active and current, I still think that this matter of $200/$300 shafts is disgusting and simply an outright greed move to take advantage of golfers. With this software we and many of the clubmakers were able to prove that in at least 95% or more of the high dollar shafts it was possible to find a similar shaft for far less cost. Graphite shafts simply do not cost that much to make. You certainly can choose far more expensive materials to use to make a shaft become expensive but you do not need to do that because there are standard modulus graphite materials that can easily be used to duplicate the bend profile, weight, torque of a HUGE percentage of the $200/$300 shafts. So wish us luck on figuring out a viable way to lay our hands on as many of the expensive shafts as possible for measurement purposes so we could eventually re constitute that data base for as many shafts as possible.


  3. Tom, My old 919THI is going great for me but I have noticed that if I shorten up on the grip I seems to get better centered hits. The shaft is 45″ which I am sure is to long for me but that is how it was built. I also have a 44″ brand X driver that is 44″ & I seem to hit it in the middle. Do yo recommend I have my 919 shortened or just keep gripping down?
    Also have a 919 FD at 43.5″ that I hit about 5 yards shorter.


    • LOUIS

      BINGO !!! You have just discovered for yourself why a shorter driver is better for the vast majority of golfers. 30 yrs ago the standard men’s driver length was 43″. No one, and I mean no one made one any longer because it was well known that longer drivers are more difficult to hit as straight or as on center as a shorter one. Unfoertunately heavy competition for sales among golf companies starting in the 80s-90s pushed the companies to go longer to try to lure more sales on the basis of golfers hitting one out of ten shots longer than ever before. Companies have known for a long time that “distance sells more golf clubs than anything else” and they are preying on this when they have shifted driver lengths up to where they are now, between 45-46″. No question whatsoever that 98% of all golfers should never be in a driver longer than 44″ and if they suffer more from accuracy issues, not longer than 43.5″. And actually as long as your grip size feels comfortable when you grip down, there is no real reason to go to the trouble of cutting it shorter.


  4. Hi Tom,
    Are all your 919 drivers the same “performance” throughout the years? For example, I have an older model with the shorter hosel…is there any benefit getting a new one? Did you do any performance changes?

    • KEVIN

      The change of the hosel length of the 919 drivers was done to incorporate a bendable hosel to offer clubmakers the chance to much more precisely custom fit a golfer for a specific lie and face angle that would help his accuracy and an aspect of consistency. Those are certainly performance elements that were affected by the change in the hosel construction. If by performance you mean distance then no, the 919 was always as close to the USGA limit for COR/CT as possible and its off center hit performance has always been at the top because of the variable thickness face design. In fact there are no new drivers and never will be any new drivers from anyone that will top what is out there now in terms of face hotness and off center hit forgiveness because every company has been at the limit for these performance factors for several years now.


    • Tom, I know this may be an impossible question but I purchased a set of your Sterling iron and LOVE them. Shot the best round of my golf life (even par at Pinehurst) in the second round of my trial. Amazing. Now I want your 919 driver but I dont have a wishon fitter anywhere near me. I have done many fittings and always end up with a mid kick shaft such as a speeder 757 or currently a hazordous Black in stiff and X flex. I bought the superlite in my Sterlings and love them. I also know my numbers very well as I have a Foresight launch monitor in my basement. driver is 108mph, AOA is 5-6 up, mid-release (8-10), launch angles are 13-17 with 1600-2000 spin. I am playing a 9 degree srixon 765 driver turned down to 8 degree. I think I want the 919 for its toe strike forgiveness but I just dont know what shaft to buy… Any suggestions?

    • STEVE

      Great to hear you are doing so well with the Sterling Irons. Wow, even at PH is really golfing the ball and shows that you definitely are a player. There are a few of the clubmakers who will work with golfers from afar in a back and forth communication to nail down your specs. Some though insist on working in person with the player. We do not have info as to who will do long distance e-fitting because we just have not asked the question. So let me recommend that you contact a handful of the best clubfitters to ask and perhaps start the dialog. The ones I recommend would be 1) Tim Mosel in New Jersey, 2) Keith Chatham in Kerrville, TX, 3) Bob Williams in Pasadena, CA, 4) Roy Nix in Columbus, GA 5) Jim McCleery in Ohio. Now here’s what you do – head to our website and look for the FIND A CLUBFITTER link at the top of the home page. Go there and type in the state/town I have listed for each. That gives you their contact info so you could email them and start the conversation. Also, as a better player it is certain you would have a more refined sense of feel for the shaft and the specs like swingweight, grip size, along with the obvious like loft. You’ll be miles ahead to do this with a shaft, swingweight, grip and loft you know for sure you like rather than to try to go with a shaft you have never hit before. Experimenting with different shafts is something best done in person and not in a back and forth from afar. Besides if you know you like a certain shaft at a specific length and swingweight with the loft and grip size/type you are used to, then you have eliminated lots of possible variables so the actual design of the head can stand forth to demonstrate itself for you. Hope this helps, and thanks so much for your interest.


  5. Tom,
    I thought I had heard you mention somewhere that you were working on a player’s driver design that may come out in the future. Is something still in the works? I assume the club would be <460 cc?
    Thank you!

    • KYLE

      Yes, the final testing is being done on the new 519SHPR driver in anticipation of having it join the product line next spring. It is smaller, running at 412cc and will be available to begin with in RH in 9* and 11* lofts. WE will keep all models in the 919THI so we can evaluate how the new 519 does when it is released before we make any other decisions about whether we tool up other models in the 519 or what. It will be done with the same type of bendable hosel as the 919 so it will be able to be adjusted by us for clubmakers to any lie from +4 up to -4 flat and any face angle from 4 open to 4 closed. Hand select will as always be available for lofts between 8.5 and 12 within the two models. I hope it is received well as another option beyond the 919.


    • Thank you Tom,
      I’m very excited to see the new design. I was planning on getting a new 919 this winter, but can manage to wait until the spring.
