Tom, I was running some fitting experiments On myself and And was trying to wrap my head around why I would swing a driver with a swing weight of E1 Almost 3 miles an hour faster than a driver of almost equal total weight, but a swing weight of D6? Would that make any sense and have you ever fit anyone into a driver with a swing weight of E1 or greater?
Drivers were the exact same length and within 5 g of each other in total weight.
Steve Fitting golfers for head weight feel, otherwise known as swingweight, is something that in all honesty would take working with the golfer over about 4-5 successive trial and experimentation sessions. Being able to perfectly find the right swingweight in one fitting session is truly a guess. You evaluate the golfer’s strength and swing tempo and you get some feedback if possible to determine whether the golfer has ever had clubs that felt either too head light or too head heavy. And then you make an educated guess for a starting swingweight on a test club and you take it… Read more »
Hi Tom, A while back in this comment section you mentioned that you were working on a driver head that would be within the CT limit but would exceed .830 COR I believe through stiffening of the head in strategic areas. Is that still something you’re working on and plan to come out with? There was also talk about a new wood shaft that was more flexible which I assume was based on the AutoFlex popularity. Am I remembering that right? Also, I wanted to post a comment about the Di595 driving iron head. How do I start a comment… Read more »
JOHN Many thanks for your interest! Starting with last things first, I see that there isn’t a comments section for the driving irons. Never knew that so if you like you can post your comment in the 919 section and then after I tell Diamond Golf’s IT man about the matter, he can transfer that to a revitalized comments section for the driving irons. Thanks for bringing that up so the omission could be noticed! The flexible low torque shaft that I have been working on is finished and on the plan for being introduced this winter. The only decision… Read more »
Thanks Tom. Can’t wait to try the shaft. As for the Di595 Driving iron head, I am a little frustrated with the specs, specifically the lie angles. 57* & 58* are more in line with driver lie angles than iron lie angles and there’s no way I’m going to make a driving iron to 43″+. In addition you’re casting the body out of 431 SS which limits the adjustability to 2*. I really want to make the 18* to 39″ and 62* lie but there’s just no way I can get to that.My swing is upright and I do play… Read more »
JOHN It has only been within the past 3-4 years that some of the companies have begun to change their iron lie specs to be much more upright. From way back when I first began to work with golf clubs in the 70s and even before that, standard lie specs for irons started with 57* on the 2 iron and then went 1* up with each iron number ending with 64* for the 9, P and S. EVERY company followed those lie specs for their std specs for over 60 years. I assume the companies that have pushed their std… Read more »
Thanks for the explanation. I’m certainly not questioning your integrity as a club designer or manufacturer but as a former owner of a small manufacturing company myself I’m acutely aware of the realities of business and cost as a factor. I’m aware that 431 can often times be bent more than 2* and have done so myself but as I haven’t been in the club making business in many years I’m reliant now on others to do this for me so I’m not sure Diamond would do this as your specs do say 2* (although my experience with Diamond has… Read more »
JOHN 304 is fine for heads that have a much wider section at the area where the bottom of the hosel fans and curves into the blade part of the head. Wedges have that because as loft increases to over 45-50*, that fan area becomes wider and can easily offset the stress of hitting down into the turf or on mats, so I have no fear of using 304 for a wedge design. But I would never use it for an iron design because with irons, that fan to blade transition area at the base of the hosel is always… Read more »
“You need to know a lot more about head shape and design before assuming anything about the use of one material vs another.”
Clearly true.
Hi Tom.
Awaiting delivery of my 771 irons (so excited).
Regarding the 919 driver, the lofts of 9, 11, 13 – have they always been those specific lofts since it’s inception?
I ask as I’ve got the 11 deg head with an UST MP5 REG SHAFT for last 8 or 9 years and want a BACK up and was thinking of the 13 deg with WHITE S2S REG as I’m getting older. A Wishon supplier has a 12 driver advertised, which I thought never existed.
ALSO
Any comparison thoughts on the Mp5 v S2S White, both regular?
Garry
WAY BACK, and I mean way back in the first year of the 919 when it was dark blue in color with a short hosel and plain sole, we had a 9, 10.5 and 12. But once the head was finished in black (second generation and onward), the lofts were RH in 9, 11, 13 and 15.5 and LH in 11. I am sorry but I do not have any empirical data on the UST shaft you ask about so I am unable to answer your question about that comparison.
TOM
Hi Tom, Thank you for the great job you are doing around golf products! I am struggling to find a driver that goes farther than my 3 wood. I’ve tried many products in golf shops, spending thought time to make people crazy about that issue 🙂 I swing my 3W around 95/100mph, carry 210/220 meters, very good smash factor. Hesitating between regular or stiff. And very much struggling to carry more than 230 meters with a driver. Question 1 would be do you see any improvement to get that extra yardage? Question 2 would be which of your driver would… Read more »
Nicolas Again, before I offer some information, I can assure you that if you contact Andre Thaon at golfnswing, he will most certainly find the best fit for your driver and woods. I guarantee that. Increasing distance with the driver and woods is first and foremost a product of clubhead speed. If you are serious and if you have no physical restrictions or impairments, choosing one of the swing speed training programs such as superspeedgolf.com will increase your swing speed, IF YOU COMMIT TO DOING IT DILIGENTLY!!! For each 1mph you can increase your driver swing speed, you will gain… Read more »
Purchased two 919 THI at 11 deg. Nice work Tom. I hit about 250 on a decent hit. Maybe the most forgiving of the big headed drivers. Perhaps I hit a little high but, still has a good roll out. Also purchased a 18 deg 775 HS hybrid. That club is amazing, I’ve never seen such roll out. Well over 220. I love the technical side of assembling a club for the individual and getting it just perfect.
RY
Thanks for stopping by and for letting us know how much you like the new clubs in your bag! It is hard to beat the 919 if I do say so myself, and it is a reason why the 919 has been in the product line for now over 15 yrs. What other golf equipment company would possibly keep a model in their line even 10-20% of that many years? Best to you in this great game!
TOM
Hi Tom mike again I’m making a driver for a next door neighbor I play with 6-10 times a year.So Tom my man this one got to work or I’m in trouble.lol!He’s 81 has bad arthritis effecting his flexibility.He has an older ping G10 driver 10.5 degrees reg. Flex.So when on the tee especially when water is in front of him he tries to lift the ball and naturally tops it into the water.Of course this driver is totally wrong for him.I want to make him the new 919 at 14 or 15 degrees with the super lite Graffaloy 44… Read more »
MIKE At 60-65 mph swing speed, go with the highest loft 919 you can get. The High Launch PLus is a spec loft of 15.5 but you could ask for hand select to see if Diamond can find a head at 16 or even 16.5. Next, no way the driver should be longer than 43.5 to 44. And keep the swingweight low, like C2-C3 low, I kid you not. At 81 with a 60-65 swing speed, the only way he could ever merit C9 would be if he has a short backswing and then a very quick abrupt start to… Read more »
The 919THI head weighs 202g and can accommodate 9g more in the weight bore. Could additional weight be added as a tip weight to allow a shorter length assembly? I am a senior with a slow swing weight and my other Wishon clubs are around C5. Would the 730cl driver be a better choice than the 15 degree 919THI?
Ron Yes, you could use a tip weight in the 919 to be able to add more weight to the head when desired. If you put 9g in the weight bore AND you put a 9g tip weight into the end of the shaft for a total of 18g added to the head, since all that mass would be in the heel area of the head, it would move the Center of Gravity off the center plane of the face and slightly toward the heel side of the face. Golfers with a clubhead speed under 100mph would not really notice… Read more »
Hi Tom,
How are you doing? Your clubs look great. Would you be able to bend the 919THI driver so that the leading edge of the hosel is in-line with the leading edge of the face? Thanks!
Damien
Damien No, it would not be possible to bend the hosel on the 919 driver to get the leading edge at the bottom of the face in line with the front wall of the hosel. With the face progression of the 919 being at 20mm, the hosel diameter at 13mm and the hosel bore at 8.6mm, what you want would require bending the hosel over 10mm and trying to keep it parallel to the leading edge. In other words, that can’t be done. It’s too much of a bend and even if you could do it, the hosel would be… Read more »
Tom,
Could you explain the process of measuring the MOI of a driver for USGA purposes?
Thank you!
Ben First go to this page – https://www.golfmechanix.com/co/items.aspx?Pdts=07 – then scroll down until you see item #070305. That is the machine specially created to measure the various different MOIs of golf clubheads. The MOI that is outlined to define the off center hit forgiveness of a clubhead is called the MOI Izz. The Izz designation dictates the fact that the MOI Izz measurement is performed to determine the MOI about the vertical axis through the center of gravity of the head. This machine has a number of different attachments to allow a clubhead to be fixtured in a manner to… Read more »
Tom, I played your ass to S2S shaft in a driver once or twice over the years. I went ahead and ordered the 77 ones this morning and I also ordered the S2 S black graphite iron shaft with them. With my seven iron swing speed being 90 to 92 miles an hour, should I tip these shafts? I am a relatively strong person, but my transition at the top is very smooth. Even slower than Hideki Matsuyama. I come to a complete pause at the top of my swing before I start down. My hands also reach my right… Read more »
Steve Your swing speed with the 7i of 90mph with a smooth transition and not a very aggressive downswing would normally say you would not tip the Black S shafts. But that really depends on your personal SENSE OF FEEL for an iron shaft before and through impact. Some players like to feel the shaft “kick” a bit – if so, then no you don’t tip and you might even back step them one club. But if you do not want to feel the shaft bend or kick coming into impact and you prefer a firm feel at impact, then… Read more »
Tom, thank you so much for your responsiveness on this page. I am currently playing your EQ one iron set, but was considering going back to a conventional length set of irons. I’ve played both the sterling version and the EQ version and then quite happy with both, but I can’t say that I’ve seen much overall game improvement. Granted, I am a four handicap already, but really trying to get to the next level or scratch. Even at my current handicap, I know enough about my swing to know I certainly don’t always hit the dead center of the… Read more »
Steve Thanks for your interesting comments about your experience with single length irons. No question that as a 4, your shot consistency with irons is likely much better than players with higher handicaps than you. It is true that single length can have more effect on improvement for players who do have issues with shot consistency that are more than just hitting several shots in a round a little off center. Your path and face angle delivery are already consistent. Most players at 8, 15, 20, and higher handicap do exhibit ranges in their path and face angle deliver and… Read more »
Thanks Tom. That is very helpful. I will look at the 565s. I just thought the extra apparent forgiveness of the 771s would always be a plus in this difficult game. 🙂 Would you say the off center hit performance on the EQs is better – equal – or less than the 565s and 771s? Its seems like most of what you are describing are aesthetic and not necessarily performance driven. With that said, I can certainly overcome a gapping issue with loft and lie but feel, consistancy and confidence are what I am chasing. That and scratch!
Steve Off center hit forgiveness wise, I truly think that there is no other iron anywhere that can match the off center hit ball speed/forgiveness of the 771. That comes because of the variable thickness + high COR face, not the MOI from the deep cavity back. 565 is not high COR nor variable thickness so it has the MOI only to drive the off center hit forgiveness. EQ is higher COR for the 5, 6, 7 but not variable thickness so it has a tiny bit from the high COR face, with most of the forgiveness coming from the… Read more »
THNK YOU! 771 it is!
TOM :
I HAVE JUST PURCHASED A USED 919THI DRIVER 9 DEGREE. IT IS WHITE WITH A POLISHED BOTTOM. IN WATCHING YOUR VIDEO, I DON’T SEE THAT VERSION MENTIONED. JUST CURIOUS IF THERE IS SOMETHING UNIQUE ABOUT THE CLUB.
TIMOTHY
The white 919 was simply a different cosmetic version of the 919THI driver. This was back in the earlier 2010s when every company was offering a white version of their current driver model. That fad lasted perhaps 2 years before it ran its course and everyone went back to black. Although most have gone to an all black finish where the entire body is chemically treated black and then the top crown is black painted over that.
TOM
Hi Tom: I have been using the 919THI driver for a few months now and I cannot say enough good things about this club. It is by far the best driver in the market. I have even purchased a second one just in case.
TIMOTHY
Well, that’s a really nice way for me to open my “work” day, to read your kind and amazing comments!!! Thanks so much for your support and may the new member of your golfing “family” continue to behave himself for you every single day!! HA!
TOM
Hi Tom,
What is the vertical COG on the face of this driver in mm?
Thank you!
BEN The balance point on the face of the 919 driver head is 38mm up from the sole. But do keep in mind that the VERTICAL CG position in a driver is virtually meaningless because we hit the driver off a tee peg, 99.9% of the time we use the club. The tee peg combined with your swing characteristics is what controls the CG position relative to the ball at impact. With other clubs that are hit off the deck, this is where vertical CG position does have a key bearing on the launch angle and spin and shot height.… Read more »
Tom I’m considering replacing my old 919 which I’ve enjoyed very much. I’m 75 so I’m swinging about 80-85 mph my 919 is shafted with a ust dhi A flex which I really like.I’ve just started a stack and tilt swing.I’ve been at the range twice with this swing.I’m liking it it seem’s powerful to me but I had some trouble with lower pulls and hooks not unusual for me even with my old swing I’m not a slicer.Thus I’m considering getting my new 919 with 15 degree loft and have you adjust the face angle to square .Tom what… Read more »
Michael I do remember your name from previous correspondence over the years and THANK YOU so much for your support and interest since the old G-smith daze!! When it comes to shafts, I have always taken the approach that is it ain’t broke, there is no need to go out and try to fix it. You said right off in your comment that you have enjoyed the UST shaft very much. Sadly I am not familiar with the exact bend profile of this UST shaft since I have not had any of those shaft samples to do a full bend… Read more »

Hi Tom,
Should the driver be the same length as woods for a true one length setup? I’m confused how that would play, given that woods play off the ground with left of centered ball placement, and drivers play off left heel while beeing teed up. How does that work with same length clubs?
Robert No, the driver has to be considered its own separate club in the set, independent of any length decisions for single length woods. The reason is because if you chose a single length for the woods based on our recommendations of between 40-41″, the driver would be too short and would cost you distance that you wouldnot want to lose. And on the other hand, if you make the woods the same length as say a 43-44″ driver, then the woods would be much too long and too difficult to control and hit with reasonable consistency. So when looking… Read more »
Hello Tom! I love the new design of the 919 THI. I have built a “Mini bomber” at 43.5″ with a 11 deg head and Aerotech Claymore MX 60 F5 shaft. One thing I noticed is that it has a more tingy sound at imapct than the old head. This is my average numbers from indoor (Trackman). — Club Speed: 107.6 mph. AoA: 2.5 up. Ball Speed: 161 mph. Smash: 1.50. Launch Ang: 12.1 deg. Spin rate: 2246 rpm. Height: 102 ft. Carry: 271 yards Total: 295.5 yards (Longest outdoor: 319 yards). I’m very happy with the build. Kind regards… Read more »
Christher
. . . . and I am very happy with your report!!! Thanks so much for letting us know! (the only thing I am sad about is that I am old so my own clubhead speed is nowhere near your 107mph!!!!! HA!)
TOM
Haha. With a “normal length” driver (45.5″) I have a clubhead speed at 115 mph. But my misses will be severe compared to this mini bomber.
I allways has been more successful with mini drivers. Had A Aeroburner Mini driver at 12 deg and 43,5″ that I could hit long and put the ball in play.
Do you know where I can buy the molds for driver and fairway wood bending? I have one of your loft and lie machines but I can’t find the molded bending kit

Dear Tom,
after 12+ years I am assessing to get some new gear. I was fitted by Mike McFadden in 2011 and have amongst others the 919THI (irons 560 MC, FW 929HS and hybrids 775 HS). On the internet, I found some pictures of the stunning design of the 719MW Driver. Could you indicate when the design will be available?
Best regards from Stuttgart, Germany
Marc
MARC MAny thanks for taking the time to search and find some information on the new 719MW driver design. It’s great to hear you were at Jakobsberg working with Mike for your fitting. He’s simply one of the best on the entire planet and in addition to the quality fit, you had the chance to be at a pretty nice place up above the river. It’s a really nice place and I am pleased to have been there four times myself over the years to speak at PGA educational seminars that Mike organized there. Thanks for your kind superlative on… Read more »
Thank you Tom for taking the time for your comprehensive answer. Mike is really outstanding. At the beginning, Mike didn’t want to get me a fitting and didn’t want to sell me any clubs. He said “you have got no Golf swing, you should work on this first”. But as I learned so much about golf and a good golf swing during our first meeting, I decided to become his student. So for about a year, I regularly drove from Stuttgart to Jakobsberg (2.5 hours!) to take lessons with Mike and he became my Pro. And after the third lesson… Read more »
MARC Thanks so much for sharing the story of your beginning with Mike. Wow, that is quite a commitment you made to drive that far on a regular basis! That certainly sounds like Mike from what you describe and I will be sure to share your post with him. He’s semi retired and still lives up on top of the hill very close to the Jakobsberg course, but the clubfitting business is run by his son in law Mario who studied under him for quite a few years. So I am confident that Mario is picking right up where Mike… Read more »
Tom
Thank you for your comprehensive answer re the 585. I will give them I try. I did not know that Mauricio is now running Mike’s former business. I know Mauricio as he received his PGA formation by the time I was at Jakobsberg with Mike in 2011.
All the best for you – and I hope for all of us, there a still some great designs from you to come!
Very warm regards from Stuttgart

Tom
In assembling an MOI matched set of clubs, do you recommend that the driver and fairway woods have the same MOI as the irons, or should it be different?
JIM Absolutely superb question Jim, because it would be logical to assume the driver/woods should have the same MOI as the irons. Glad you asked it so I can have a chance to answer and explain why. In a successful full MOI matching fitting experience, the driver and woods tend to be on average, 75 g-cm2 higher in MOI than what the irons are. The reason for this is because in the full set, there is usually a big gap in length between the shortest wood and the longest iron. And length is a much more influential factor in determining… Read more »
Tom
Thanks for your detailed response. One other question I have is how close in g-cm2 do the clubs need to be to be considered matched? What would the range in gm-cm2 be where one could call the clubs matched?
JIM
My pleasure. Clubs in an MOI matched set that are within 5-10 g-cm2 of each other are considered to be EXTREMELY well matched. Anything under 20 is OK, but 10-15 is really a creditable range to be in for a proper MOI matched set. I believe that no one could detect a difference of 5-10, not even a tour player because a gram-cm2 is very, very small.
TOM
Tom
The new 2023 hybrids and fairways looks great. Can’t wait to test them out!
I also read there is a new 919 and 719 driver on the way. I’m playing the current 919 so I was curious how the new drivers differ in design and performance. Always nice to hear this from the brain behind the product!
Johan The new 919THI is primarily a cosmetic upgrade to the model. The previous version had been in the line for quite a few years and we felt it was time for a makeover, so to speak! All of the performance elements and features – the variable thickness cup face construction, the bendable hosel, the shape, the OI, the CG positions, etc., are all the same as before because quite honestly, I have felt for some time that I could never design a better PERFORMING driver than the 919. So I didn’t try when it was time to do this… Read more »
And the statement above shows once again why Wishon is THE brand to go to !! Other companies would wax lyrical about how their new carbon, speed slot, jailbreak, adjustable perimeter weighting etc etc technology will add MILES to your drives (which of course, is all just marketing hype). Tom Wishon tells it as it is, fundamentally a cosmetic upgrade to a driver that is already, arguably, the best on the market bar none. If you are thinking about getting custom fit, stop thinking, find your nearest Wishon approved club fitter and make the call. I have gamed 919THI, 365… Read more »
Hi Tom,

Just a heads up, the new 719MW is now available!
Tom, I’m going to start working with Ed Ellis in a few days to custom fit driver for my bag. I have Wishon single length clubs from lob wedge to 4 wood now and find them key to my game. I’ve saved driver for last. I’m wondering if recent experience with my current TaylorMade Burner 10-degree driver and my Wishon 4 wood is helping me understand your premise about driver loft for senior players like me. My swing speed with driver is about 85-90, sometimes a bit more. I can reach 200-205 yards with my driver choked down to 43″.… Read more »
STEVE With an 85-90mph driver clubhead speed, DEPENDING ON YOUR ANGLE OF ATTACK INTO THE BALL, it should be possible to optimize your driver carry distance to be around 220-225. But as I said, that all depends on the A of A. So when you work with Ed, assuming you’ll be on a decent launch monitor, watch that A of A to see what it is. 220-225 should be possible as long as your A of A is not downward to any degree. But if you are level 0 with the A of A, a launch angle of around 14*… Read more »
Thanks for the explanation, Tom. I hit a couple practice drives this evening ending my short game practice. I paid attention to the ball flight and its apex. I topped out at about 65 feet. Carry distance was 200 and 208 yards. I’ll be curious what Ed and I figure out about my angle of attack. It’s going to be fun. Thanks again.
Steve
Steve
Yes I will be interested to hear how it goes and what Ed comes up with for you. 65 feet for a driver apex seems a bit low for your clubhead speed, in terms of max carry it is I think. But driver shot height is a trick thing because you have to gear it to the firmness/softness of the fairway. Dry, firm fairway conditions always calls for a lower launch angle and height than what would be optimal for max carry to maximize total distance. Wet, lush fairways are all about maxing carry distance. Have fun!
TOM
I’ll let you know Tom. Thanks.
Hey Tom, I’ve been using an early model (~2013) 919THI w/SP700 face for quite a while now. I’ve always been a huge fan of drivers with SP700 faces, I’m apparently one of the few golfers who can notice an appreciable difference compared to materials like 6-4 or even 15-3-3-3. Almost every driver that I’ve ever truly loved over the years, has turned out to have an SP700 face (which I often didn’t know before I fell in love with it). I’ll be honest, I wasn’t a fan of the feel/sound of the 6-4 face that the 919THI switched to back… Read more »
JAMES The only way one could tell one of the older 919s like that would be by its sole design and color. The early 919s all had a plain sole, no swoops, ledges, raised elements of any sort, and it was painted in a dark blue finish. Outside of that one would need to have a $3000 ultrasonic thickness gauge to do a face thickness measurement to tell the difference since the early SP700 faces were thinner, owing to the fact the material had a higher yield and tensile strength than 6/4 so it had to be a little thinner… Read more »
I know the first gen with the blue crown and yellow half-moon shape had an SP700 face, and that one is easily distinguishable because it looks different. But didn’t the 2nd gen also have an SP700 face for a little while? I thought the change to 6-4 happened sometime around 2015, but the 2nd gen redesign happened in around 2011. So wouldn’t any 2nd gen head from 2011-2015 have an SP700 face? But even so, you’re saying there would be no way to tell since the heads are cosmetically identical after the 6-4 face material change?
JAMES I honestly cannot tell you precisely when the change from SP700 came to 6/4 for the face of the 919. I simply cannot remember that in the face of all the many clubhead design projects and development management I have done over the many years I have been doing this. As I said in the other post, the only way to tell is with an ultrasonic thickness gauge (or by cutting the face off to do an alloy ID for the faces!!) since the SP700 face would be slightly thinner due to its higher strength. But again, the COR… Read more »
I wanted to post a follow-up comment on this, as I think I’ve identified a way to distinguish the SP700 heads to the newer 6-4 faced heads. When the 919 was first redesigned in 2011, it kept the SP700 face as well as the short hosel. Then when it was updated again in 2015 with the longer hosel, I believe that’s when the face material was changed as well. So, correct me if I’m wrong, but shouldn’t that mean any head which has the shorter hosel should also have the SP700 face? Based on my research, with the help of… Read more »
Actually, a correction to my last comment. It looks like the bendable hosel was added in late 2013, which is apparently when you also created new plasma-welding tooling dies. At that same time, the verbiage “919THI face forged from SP700 titanium” was removed from the bullet points on the product page, although in the product images which show all of the detailed specs it still said “Face Material: SP700 Titanium”.
