Tom- New to your site and enjoying it immensely. Is there a practical limit to how short your 919THI driver can be built and still “perform” both in terms of distance and feel (recognizing that factors such as shaft and grip weights, swing speed, etc. impact things)? In effect, at some shortened length, would the driver likely be inferior to a strong 3-wood properly fit, for example? I’m 67 with diminishing club head speed and trending away from my low to mid single digit historical handicap range! Playing forward tees these days and enjoying the game more! FYI: I intend… Read more »
Dennis Many thanks for your interest. We’ve been providing the absolute facts about golf club performance and clubfitting technology for a long time simply because the standard business model of selling in standard form off the rack done by ALL of the big companies is just not the best for the vast majority of golfers. There is definitely a point in shortening the driver at which a golfer will see a decrease in distance because of the effect of a much shorter length on clubhead speed. I see this for most male players at a length under 43″. At lengths… Read more »
Tom, thanks so much for your rapid and enlightening response. I may just follow your lead and replicate your 12-club setup, possibly with the only variation being a 7-wood (21*?) instead of the 21* hybrid. May have some shaft questions for you next! In meantime, I am binge-reading your one-of-a-kind web site.
Thanks Dennis, happy to help in anyway I can. Since you are interested in the information, I can leak that I will have a brand new book, possibly my last since I am getting longer in tooth (!), which will be out in a couple of months. This will be part fun with a section telling many of the stories of my varied experiences through my career, but the second part should be of interest to you because it is an encapsulation of the main technical points I have discovered in my work that are important to the performance, design… Read more »
Hi Tom.
I was hoping you could explain the difference between an investment cast titanium driver vs. a forged one and if can the face of a driver can be cast? Which one is more precise and of higher quality? In the real world is there any difference in performance?
Which method of construction did you choose for the 919?
Thanks!
NATHAN INvestment casting is usually chosen for the method of manufacture for a ti driver if the driver has more intricate shape features on the head such as any sharp angles of ledges or surface changes of the cosmetics or weight distribution of the design. Very intricate shape features cannot be made by forging or plate forming and can only be made by casting. But casting typically leaves the titanium with more voids and inclusions (tiny microscopic holes) which can decrease the toughness or durability of the head a slight amount. So if the designer knows the head could be… Read more »
What I want to know is when is Tom going to start using “AI” and wind tunnels to develop his next SUPER driver head, isn’t that the wave of the future, lol…I’m just kidding of course and putting a dig into the ribs of the Callaway and TMs of the world. Actually on a good note (if you can call it that) I heard in the wind about some of these manufactures may be going back to glued hosel/shafts in the near future, hmmm, wonder why that would be. So what’s old is new again………….I wonder if “AI” led them… Read more »
Walter Why use ARTIFICIAL intelligence when you have 34 some years of REAL intelligence, developed and acquired from all those many clubhead and driver models that I have designed in my career!!? HA!! This is so much like I predicted a few years ago in my writings, in which I stated that as of around the mid 2010s, we who do this kind of work fot to the point we have used up all of the driver design technology that there is to be discovered. The science of driver head performance is most definitely finite. Every coherent, meaningful point of… Read more »
Hello Tom, I am 62 and have a 15,5 HLP with a S2S Blue 45 at 43,5 inches. When I began to use it I was 24 of index and now I am 16.5. My carry was 155 yards, it is now 170 yards. And my trajectories are very high. Could I get 10-20 extra yards with a new shaft (S2S White, etc. ) or do I have to change the driver (13,5 ?) Thank you
VINCE There are two possibilities for getting a little bit more distance. If you feel that your shot height with the 15.5 HLP driver is much too high and you see the ball never roll much at all after landing, you can drop the loft down to 13 and from the lower trajectory you might get enough roll after landing to make your TOTAL distance more than what you see now from the 919 HLP driver. Second, and this one is a little dangerous, if you go longer in length you should see a little increase in clubhead speed which… Read more »
Hi Tom
Can you tell me how far back the COG is on a 919THI driver. I ask as I have an M3 which spins too much unless I slide the weights to the very front.
Thank you in advance, Phil
PHIL
The CG on the 919THI is located very close to 37mm back from the leading edge at the bottom of the face, depending on the loft model you have. If you have the 9* model it is 36.75mm back from the leading edge, and on the 11* it is 37.25mm back from the leading edge.
TOM
Hi Tom,
is this clubhead suitable for a high swing speed high spin player?
Thanks,
Julian
JULIAN The 919 passes air cannon durability testing easily for a 120mph clubhead speedbut if you are up at 125 and higher then you have to expect that the head is approaching its upper limit of normal durability and would/could fatigue over the course of a year to two. Spin wise I have always felt the 919 performed better than most any other driver for higher speed players because of its GRT face design. Pretty much every company uses a vertical face roll radius of 10″ to 12″, with maybe a couple at 14″. I use a 20″ vertical face… Read more »
Hi Tom, thank you for the reply to my earlier post! No harm in the delayed response, i hope you were on vacation! Thank for for the information as well as the possible shaft recommendations. I do believe the shaft was the “firm” version, however I will check with my club fitter/builder (Tim Mosel). I will ask him about the S2S white (I have only tried you S2S black shaft). I will also give the 43.5 in shaft a try as well. One more question I have is, I was fit into a 12 degree driver for optimal distance. This… Read more »
ERIC Yes it was a vacation, which now that I am semi retired, I am hooked on and need more and more of!! HA ! As long as they include golf, and as long as I don’t play badly too ! Since you said you have a 108mph clubhead speed, I can’t imagine you ever wanting to try a driver loft as high as 16*. That would only be applicable if you hit 3w off the tee on a tight hole. For an actual full out first string driver I would think you’d lose distance with the 16* bigly, even… Read more »
Hi Tom, love your products! Had a question regarding shafts for this club. I am working with a club fitter in my area and trying to come up with the right build. I’ve Never and still can’t accurately play a longer shafted driver so I tried the following build and loved it: 919 head Matrix studio 84 shaft at 42.5 inches, approx 265 cpm. Not sure how it was tipped but I could get that info if necessary 16 degree loft Unsure of face angle Well the studio 84 shaft is no longer available and I got along great with… Read more »
ERIC Sorry for the delay in responding as I was out of town for about a week and a half. I enjoy doing the responses to help golfers so no one else was covering for me on the comments responses while I was gone. Hope that it did not inconvenience you too much. In searching our data base of shaft bend profiles, the only Matrix Studio 84 shaft we have in the DB is the Studio 84 in the Firm flex. If that is in fact the actual one you have in your driver, the software shows that these other… Read more »
Tom what happened to the 519SHPR.. did it ever get released. Was there a delay? Thanks for info. Just a fan always interested in your designs. Thanks
JOHN Launching a new clubhead is not something we take lightly here at Wishon Golf. Due to production issues with the samples and first batches of clubheads which arrived here at Diamond Golf HQ in early Spring, we have decided to delay the launch. The main issue was with the strength of lofts, which would make on-spec handpicking a real problem. There were also quality issues which left us no option but to halt launching to our customers who, as we know, demand a quality product from Wishon Golf. So we have gone back to the factory to work on… Read more »
That’s okay it will give me the time to try out the new THi 919 driver and the F/D before I decide to try the new driver head. So far they’re the best I have ever tried. But please do let us know when the new head is ready for release.
Walter
We’ll inform everyone by email and the website will announce it as well. Thanks much,
TOM
Hi Tom, I am demoing a 919 THI driver right now in LH at 11 degrees. Is there any way I can tweak that loft down to about 9.5 degrees? Is that a possibility? I have the Sterling Irons (which I love) now I just want to complete the set, but that 11 degrees is a tad high. Thank you.
Dallas
Dallas Not conveniently, but it is possible. All my driver, wood and hybrid models are designed with a bendable hosel but I did that primarily to offer custom changes in lie angle and face angle, not loft. However, if the hosel of the 11* model is bent 1.5* open, then if you always grip the driver so you address the ball with the face square to the target line, the loft will now be changed to 9.5*. Doing this requires not soling the head on the ground as you would have to hold the head square to the target. That… Read more »
Tom
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?
Thanks
LINCOLN 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… Read more »
Tom
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.
LINCOLN 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… Read more »
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.
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… Read more »
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.
Thanks,
Louis
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… Read more »
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… Read more »
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… Read more »
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… Read more »
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
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… Read more »
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.
Kyle
Hi Tom,
What are your thoughts regarding why it is important to fit a golfer to the correct lie angle relative to drivers, fairway woods and hybrids. I can find many articles that refer to its importance for irons, but nothing definitive in the case of drivers, fairways and hybrids. My irons are bent to 3* flat and I’m wondering how insistent I need to be with my fitter on having the lie angles of my other clubs adjusted.
MIKE Good question and I am happy to answer for you. With the irons lie is all about accuracy – as loft increases the face is tilted more off line when the lie is not fit right to make the sole travel level to the ground through impact. With the driver and woods it is different. For one, with less loft the misdirection angle is not so much and this is also muted by the fact the fairway is much wider than a typical green. But there is a definite importance in having the lie of the driver and woods… Read more »
I am very interested in making my next driver a Tom Wishon product, however I’d like to know how this compares to the Ping G400 and Callaway Rogue, both very forgiving and long drivers. Thanks!!
Mr Fowlkes Thank you very much for your interest. While I would put the 919THI up against any driver ever made anywhere by any company, that won’t mean anything to you coming from me. Of course you would think I would say that. So the only possible way you can have a chance to see if such a move would be worth your time and money would be to contact a custom clubmaker in your area to see if you can test hit one of the 919’s hopefully in test specs that would be reasonably well fit to what you… Read more »
Hi Tom I’ve just read your book In Search of the perfect club which I found fascinating,so much so that I wet to the local range and got them to build me a driver with 13 1/2 degree loft and a softer lighter shaft for me to try against my ping 10 1/2 regular shafted driver. Tom it was a no brainer my swing speed is around 80 these days at age 65,the difference in performance was so much better.The trajectory was higher ,the strike felt very solid and the carry distance greater.All this from a club assembled in minutes… Read more »
Peter Thank you very much for being so interested in golf club performance that you decided to read one of my books! That’s very nice of you and I am so pleased to hear that you acted on some of what you read and found the results to be positive for your game. I’ve been digging into the performance of golf clubs since 1974 and I can tell you three things — I don’t get tired of learning something new about club technology, I really enjoy sharing what I learn along the way (which is why I write) and the… Read more »
Tom do you still have the 919 in a offset head
Stephen No I am sorry but the 919 Offset was discontinued last year. As is the case whenever any model is discontinued, it is because the demand from the clubmakers just is not enough to sustain the requirements for production and inventory. Once we created the bendable hosel on the non offset 919 driver heads, that allowed clubmakers to bend more of a closed face angle to reduce a slice tendency. The Offset model’s main reason for existence was to help reduce a slice. So with the bendable hosel there really was no need to keep the offset, also since… Read more »
Tom,another question:
The specs state the Bore Depth to be 35 mm and the Swingweight Bore depth to be 15 mm.I had understood the 35 mm was available for shaft insertion and another 15 mm was there for the weight plug insertion.
I find that after having inserted the cylindrical tungsten weight,the shaft can only be inserted upto 20 mm?
Can you please confirm?
Tariq The hosel bore depth of the 919 is 35mm and the weight bore depth is 15mm. Both do have a +/-1mm tolerance so they could be 34 and 14 or 36 and 16. I would be highly unlikely to impossible for the actual bore depth to be 20mm due to all of the procedures and checks that are instituted in the production of these heads. The hosels are made separately by machining and then welded on to the body of the head so it just is completely unlikely for a mistake of this magnitude to ever be able to… Read more »
Tom, This is used head. I believe the previous owner ,in trying to clean out the hosel,drilled past the 35 mm mark right through the bottom of the weight cavity. Theoretically if a weight were to now be inserted into the hosel it would slide right down to the bottom of the head,but that is not happening! At the 35 mm mark there has formed a metal circle which reduces the diameter of the hosel such that it prevents the weight plug to descend further.Hence my comment that only 20 mm was left when I inserted the weight plug. I… Read more »
Tariq Thanks so much for the additional information. That helps me a lot to explain things better for you to try to help. When we put the weight bore into any woodhead, it is made by carefully welding a thin wall cylinder of 7.5mm diameter and 15mm depth to the bottom of the shafting bore. This of course has to be done before all of the body pieces are welded to form the whole head. There is a small lip made at the bottom of the shafting bore that is there to stop the tip of the shaft during normal… Read more »
Hi Tom,
I’ve a 911 THI 11degrees which I love. Recently I bought another 11 degree head on a golf forum and the hosel on this one is about 1/2 inch longer thanmy current head.
My question is: Is the new head a more recent model which better accomodates hosel bending? And does that mean my current head will be more difficult to bend?
Thanks
Tariq
All of the 919 driver heads made with the longer length hosel are bendable. The non bendable early version of the 919 had a much, much shorter hosel length.
TOM
Tom when measuring this driver in the spec gauge I think I can see how it soled for face angle but maybe you can make it clearer. When I put it in and press down it opens the face up to a reasonable degree and then I have to push back on it to get it to open up more. When measuring the lie is it the dot in the center of the face thats used?
Andrew
This is so hard to try to use only written words to explain how to fixture the 919 for proper specs measurement. Since I can’t show you in person I will try to send you some photos to your gmail address to try to help. But I just got back from being away for a week so I need a day or two to catch up on the things that happened before your question arrived. So forgive me for being a few days late with this.
TOM
Hi Tom,
I hope you are well.
Last time we spoke was after I was fitted for the 575 combo set with a 775 in the 3. In the 775 I was put in your black hybrid shaft 65-80 swing speed.
I’m going for a driver fitting but unfortunately the fitter doesn’t have any of your equipment.
So he doesn’t try to put in to a shaft that costs the earth is there any shaft you would recommend.
Thanks for your help.
Richard.
RICHARD If the Black hybrid shaft plays and performs and feels good to you, then it would mean your swing characteristics would match up well to our S2S Black 65 in the same letter flex that you have in the Black hybrid shaft. 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… Read more »
Hello TOM, how are you? I have talked with you through this site a few times, with regards to the amazing Sterling Irons discussions page, and I had a question about the 919thi. When it comes to the 11 degree, which is made with the .5 hook face angle, we could have a fitter/builder change that angle to a square face angle right? I apologize if this is a stupid question, lol, as I do see in the clubhead specs that you’re able to change the face angle up to 4 degrees… but I needed to make sure before I… Read more »
JAKE Very good and thank you for asking! The reason I put the special softer titanium material hosel on the 919 driver heads is so the head can be custom bent to change the lie and the face angle to better fit golfers. With it, any of the 919 models can be changed within a +/-4* range from the design specs for the face angle and the lie angle. So yes, the 919-11 can be square, easily. For something like a 1/2* only change, it is also possible for the 919-11 to be ordered with a Hand Select to find… Read more »
Thanks TOM, as usual you are so informative (and timely) with your replies.
While I was out I called around and you’re right, nobody can help me with bending the driver heads. I was really hoping one of your resellers had the ability… but no luck there either.
I will have to find a way to get a head direct from diamond with the right setup.
Thanks again,
Jake
Finally found a 8* driver and had it bent 1 1/2 degree closed and loving it. Hit it straight or slight fade. Finding fairways finally. I struggle with slice and had learned to manipulate my wrist and clubface with my old callaway but the closed face on my wishon make MY swing work so much easier. Really don’t understand why bending clubs isn’t more popular.
Allen Great to hear that you are finding fairways with the newly adjusted driver. That’s precisely why I developed that feature for the 919 drivers as well as for the majority of the fairway woods and hybrids in my line. The other companies do not do this because, 1) they don’t have any real experience with using face angle as an accuracy enhancement spec on a driver/wood/hybrid. Over the years it’s evident that these other companies do not even state a face angle spec for their drivers, woods and hybrids. Why is because to do that would require them to… Read more »
Hello Tom… I’ve read your comments above regarding the weight bore at the bottom of the hosel on the 919 THI. Can you tell me what exactly it looks like? Is there a hosel plug that I have to remove before I can access the weight bore? The reason I’m asking is because I bought a used 919 THI head from eBay last year, but never could get the swing weight of the finished club down to an acceptable level since the head by itself weighs a whopping 212 grams! So I’m wondering if the previous owner had added weight… Read more »
CHRIS First keep in mind that every bit of the area inside the driver head is open and hollow. The hosel weight bore is a thin walled steel cylinder of 7.5mm ID and 15mm length that is welded carefully to the underside of the hosel. There is no cover on the weight bore. Down at the bottom of the shafting bore is a lip that stops the shaft tip at a bore depth of 35mm. The weight bore is open at the bottom of the shafting bore but because of the lip and the fact the weight bore is 7.5mm… Read more »
Hello again, Tom… I wanted to thank you for getting back to me so quickly, and for providing such a detailed explanation on how to remove the tungsten weight. I am very happy to report that, by following your instructions, I was able to remove the weight!! And all without doing any damage whatsoever to the head! Everything you said was spot on– from the flat screwdriver slot at the top, to heating and twisting the weight, and finally, banging the hosel on a piece of wood. It all worked perfectly! The head now weighs a very manageable 203 grams.… Read more »
CHRIS
HEY !! how about that !! Very glad to hear you were successful in getting the weight out of the head. You must have a higher level of patience than others who I have counseled on this and gave up (too soon probably !!)
Good deal and have fun playing and experimenting with the club !
TOM
