Hi Tom,
Is there any update on the timeframe for the replacement of these 590DIH heads?
I look forward to your response.
Kind regards,

Hi Tom, Why are those 590DIH clubs discontinued ?

Tom Wishon

90% of the time when a model is discontinued, the reason is simply because of lack of popularity and demand among the clubmakers and their customers. The other part of the time it is because the production factory that was making a model encountered problems such as a lack of enough business that resulted in them closing down. The world of the clubhead production factories is a very competitive industry and companies do disappear every so often. But we are working on a little different direction in the area of driving irons so we will not be without that option… Read more »


Hi Tom,
I often see clubs on Ebay for sale that are marketed as “Tour Issue” models. I have heard for years that the pros have better clubs. Thus, assuming an average weekend golfer can find a club (or a set) with the lofts, lie, and length he or she likes, is there any advantage to these clubs over those purchased at golf pro shops?
Would tour issue clubs likely improve the average golfer’s score?

Tom Wishon

HOWARD For every company that pays pros to play their equipment, they have a department that does nothing but build the clubs their contract pros will play. Most of the time the heads for the tour program will be the same as those made for the standard business of the company. But there most certainly are pros who require specs on the heads for their clubs which are different than some of the specs on the heads used for the store business. It might be a different face angle, different weighting, you name it. if the pro wants something different… Read more »

Dear Tom, Just thought I’d write a quick note of praise for the 590DIH! I had Bob Spicer of RJS Custom Clubs put me together a 2 iron with a DG105 stiff shaft. Haven’t seen smash factors of 1.5 with an iron before, but that’s what we’re seeing on flightscope! Very impressive!!! Carry is between 245-250 on good strikes, around 28-29 yard peak height. Great to have a club I can feel confident of keeping straight and getting good distance. I call it “The Zinger” for the sound it makes when you get it right out of the middle. One… Read more »

Tom Wishon

ROB Thanks so much for taking the time to share your experience with the 590 driving iron with us !! We do appreciate that and we are very pleased to know that the club has put a little bigger smile on your face when you hit it ! As far as the clubhead speed between your old 1 iron and the driving iron, here are the areas where one club can cause that for a golfer. 1) Total weight – if the 1 iron is lighter in overall weight, that can bring about a higher speed; 2) Combination of the… Read more »

Hi Tom,
The Stirling irons are working out great. With c225 yards from the 4 iron off the tee with great consistency, I’d like to buy a Stirling 3 iron with c14o of loft.
Hope you can you help with this.

Tom Wishon

JOHN I am very pleased to hear that you are doing so well with the Sterling Irons ! Wow, to be able to get 225 with the 4 iron means you are at the very top of the list of golfers with a high swing speed !! That’s great ! Unfortunately I cannot say that there would be an iron with 14* loft added to the set. And the honest reason is that there would not likely be more than a small number of players like you with a much,much higher than normal swing speed who could hit the club… Read more »

John Barnes

Thanks for your reply Tom. Do you think it would be better to buy a 590DIH 2 driving iron & have it de-lofted by 2 degress & cut to match the Stirling irons length for max distance or should I buy another Stirling 4 iron & have that de-lofted by the max of c3o. Appreciate your view on this. Regards John

Tom Wishon

JOHN IN total and complete honesty, I would not recommend doing either because both have very serious drawbacks. With the 590, it is VERY difficult to bend for any change in loft so trying to get that down two degs would be tough to do. Even if that is done, the 590 #2 is a 232g headweight. TO make the head work with a Sterling single length set would require that head to get up to 274+ grams. There is just no good way to add that much weight to that or to any iron head. If you try a… Read more »

Andy Watson

Hey Tom,
I would like a 2-iron (18 degree) club at a 63.5 degree lie angle. I have a set of single lengths that are custom fit to my wtf measurement, and are all a 63.5 degree lie angle. Is this possible? I need a driving iron that i can swing faster. Thanks!

Tom Wishon

ANDY I’d say it would be pretty difficult to impossible to find a 2 iron head that could be suitable for the headweight you would need as well as to be able to be bent that much upright to match the rest of the heads in your set. First of all, none of the single length companies make a 2 iron so you would have to use a 2 iron designed for use in a conventional lengths set. In such a case the 2 iron head would be likely around 232 grams in weight. if your single length set is… Read more »


I’m looking into options for my son. He is an aspiring College golfer that wants to take his 2 hybrid out of the bag and replace it with a 2-iron. Which shaft would be better for one of your driving iron heads? A hybrid Shaft or an iron shaft? Thanks.

Tom Wishon

KEITH Not knowing why your son might wish to replace his 2H with a 2i, I have to guess that perhaps a part of the reason could be that he feels he hits the 2H higher and with less control than he might with the 2 iron. If so then the driving iron would best be shafted with an iron shaft, using the same exact shaft that he has in his iron set and built to the same swingweight as well. The 590DIH driving irons are designed and mfg’d with an 0.335″ parallel bore to accept one of our hybrid… Read more »

Robert Riedel

Just got a custom set of your Sterlings 4-LW made and I was wondering if you think the 2 or 3 590DIH would be a better gap filler between my 3 wood (15 degree) and the Sterling 4 iron (19 degree) It says 18 for the 2 and 21 for the 3 iron. Any thoughts/recommendations from your experience? I am a scratch golfer with a smooth 110 mps driver swing. Thanks!

Tom Wishon

Robert: Me thinking personally as a golfer, I am not a big fan of low loft irons because they require a pretty healthy clubhead speed to get the ball elevated high enough to carry the shot far enough. This is because irons always have their center of gravity located right behind the face. Fwy woods and hybrids tend to do better at lower lofts than irons of the same loft because with their broader body, their CG is much farther back from the face. This causes the shot to be able to be elevated a little higher, and a little… Read more »


Amen to that! Thanks Tom


Thanks Tom for the comeback on the 590DIHs. So much to think about and analyze! I do use standard length clubs in my hybrids and I am working with Sherm Haworth on figuring out the best configuration of my bag. Right now, I am nibbling around the edges of my set, first with the 919 driver, and then SR2(5) putter, before I get to jumping in to the iron set I ultimately settle on. Believe me, we the people of skeptical big marketing schemes really do appreciate you and your tremendous network of club fitters who help us make sound,… Read more »

Tom Wishon

Here is the very best advice I can give you, hands down. Ask Sherm what he recommends for your set makeup and specs and don’t doubt one word of what he says. I put Sherm in the top five of clubfitter/clubmakers in the whole world. No doubt about that. So when I read you were working with him, I knew the answer immediately to your dilemma !


Hi Tom, I currently use a 3 & 4 hybrid and my irons start at the 5. Occasionally I will dig out a very old Titleist Tour Model 3 iron (1990 vintage) as a means to drive it straight, long and more importantly accurate. I like using the 24 degree 4 hybrid for trouble from the rough, and to hit a nice long draw, about 190 yards. I don’t like it for accurate drives though from the tee, so I am thinking having a driving iron made for me. Question becomes comparing distances, 3, 4, or 5? What are your… Read more »

Tom Wishon

MIKE I can’t tell you for sure about distances you would achieve with the Sterling low loft irons because I do not know your clubhead speed OR your angle of attack on the downswing. Those two things tell the whole story about how far you would hit any club. My guess is that if you can hit a 24* hybrid at 190 yds ( I don’t know the length of that hybrid though which is critical to a correct evaluation ) that you should be able to elevate a 23* iron at 36.5″ length, but you may not be able… Read more »

Warren Watt

Hi Tom. I am currently using your 771 irons with Wishon Superlite stiff flex tipped 1in. As well as a 2 775 hybrid with Wishon white hybrid stiff shaft. I am looking for a driving iron and shaft that will give me a low ball flight? Currently I hit the ball pretty high and would like a dependable driving iron giving me a low penetrating ball flight! I am very happy with the current makeup of my set just need this add on. Any recommendations?

Tom Wishon

WARREN thanks very much for your post and your interest in our work. we appreciate that very much. Last year we did introduce the 590DIH driving irons in a #2 (18*), #3 (21*) and #4 (24*) in right hand. They are a high COR face design with variable thickness face construction, the same as what we did in the 771CSI irons. While driving irons don’t sell in the volume other models do because it is a specialty model, I can tell you the comments we have had from clubmakers and golfers who have bought one of them have been extremely… Read more »


Can you recommend a shaft or shaft to help with a lower more penetrating ball flight…. Jacques Lavack fit me for my WIshon set

Tom Wishon

Warren It is not possible for us by email to recommend a shaft for a golfer. Proper shaft fitting requires knowing the clubhead speed AND seeing the golfer’s swing motion to evaluate their downswing transition force, downswing tempo, point of release and then to talk to them a lot to determine if they have a specific like and dislike about the bending feel of the shaft in their clubs from their playing experience. Jacques is one of the very best and most experienced clubfitters in all of North America so I would strongly recommend that you see him to have… Read more »


Hi Tom,
Tweo weeks ago i updated my bag with teh SLI irons. I am looking to replace my hybrids with the Driving Irons. My length is 37″in my SLI irons. I was thinking about using 37,5″ for the 4and 3 Driving iron. Can you give me some advice? Thanks Alex

Tom Wishon

ALEX: it certainly is a viable choice to use the 590DIH driving irons to replace normal hybrids. but I would not recommend doing them at 37″ because for the low lofts of the 590 DI’s, the short of a length may reduce your clubhead speed enough that it would be difficult for you to achieve a proper shot height to maximize the carry distance of the irons. Because these 590’s are NOT at the 274 gram headweight of the single length irons, you cannot make them to be anywhere close to the length of the Sterling irons – they’d be… Read more »


Hi Tom, I am going to be replacing my hybrids in the next week or two. My complaint with them is that I always felt I hit them too high. Comparing the 590’s vs the 335 hybrids (which I gather is the lower hitting of your hybrids) is there any discernible difference between these clubs – or, what are the differences? Thanks!

Tom Wishon

SEAN Because of the lower and more rear located center of gravity in a hybrid vs an iron, this is why some players do hit hybrids higher and sometimes even fight ballooning the ball a bit with them. Especially those players with higher than average clubhead speed. and also with the 335’s because they do have a lower CG than our other hybrid, the 775HS. Couple of things you can try. One would be if you like the looks, shape of the hybrid behind the ball, you could ream the bore to 0.355 taper or to 0.370 parallel and install… Read more »

Ben Doyle

Hi Tom
I am a pro from Northern Ireland, just recently fitted and put together a 590 2 iron head with the s2 blank hybrid shaft and have to say I am really impressed. The best driving iron I’ve ever hit, great distance and forgiveness. Great club.

Tom Wishon

Thank you Ben, we appreciate the feedback very much! We’ve very pleased to hear you like the performance of the model !


How might the design of the 590DIH driving irons complement the ‘long’ end (in distance) of the Sterling single length set? I.e., do you think a 3i in the 590DIH (presumably with some customization of loft and lie, as well as thoughtful choice of shaft) might be a logical extension or complement to the long end of the sterling set? Thanks for your view and insights on this.

Tom Wishon

SCOTT First off, my sincere apology for the big delay in responding. The notification feature for posts and comments was not working so we haven’t seen the posts being made here for us to respond. That’s a big Ooops. Sorry about that. While the high COR face and low CG of the 590 driving irons most certainly would be a good way to design a lower loft head in the Sterling set, the actual 590’s themselves would be tough to try to use to add on a lower loft end to the set. They’re too light and too flat to… Read more »


Thanks! That makes sense, was just trying to recycle a shaft but I’ll just pick up a hybrid one when I order the head.
Thanks again!


What would the proper tipping instructions be when using the 2 iron if I’m installed one of your 85 gram X black shafts?

Tom Wishon

AUSTIN While the 590DIH driving irons are made with a 0.335″ bore, my intent was for them to be used with the hybrid shafts in our shaft design line. Or the hosel bore could be reamed to 0.355 or 0.370 so that an iron shaft could be used and from that, allow the golfer to match the shaft in the driving iron to the shafts in his irons. Certainly it is possible to use a wood shaft in the 590s. But in doing so, that sort of puts the player out into the ozone/hinterlands when it comes to how to… Read more »


Hi Tom,
what is the right way to go in terms of shaft? Last year I was fitted for the Black series of shafts which suits me very well. Should I take a normal iron shaft or should I take a hybrid shaft for my 590DIH?
Thank you for your answer and the amazing work of TWGT,

Tom Wishon

ED: In all honesty, I would first go the route of the hybrid shaft. The driving irons are much lower in loft vs your other irons and that right there no matter the high COR face or the sole design is going to make it more work to get the ball well up in the air to fly. Having a little help in the form of the hybrid shaft can make a difference for some to many golfers over jumping right in with the same iron shaft they use in the irons. This is why I designed the 590s with… Read more »


Hi Tom, I am currently gaming a set of 771 irons from 6-AW. What will be the performance difference or characteristic if I add a 5 irons 771 as compared to a 5 iron loft590DIH Driving Iron (4 irons bend to 26 degree), assuming that the shaft, length and MOI remain the same….. thanks

Tom Wishon

FLASH In all honesty the performance difference for distance between the 771-5 iron and a 590-4 bent to 5 iron loft would not be any different. Perhaps there would be a TINY increase in off center hit performance with the 771 over the 590 because the face area size of the 771 is a little larger than that of the 590. So that could generate a very small increase in the off center hit variable thickness face flexing from the slightly larger area of the 771. But at best it would be VERY small and probably not really noticeable to… Read more »


No left hand? 🙁

Tom Wishon

Sorry about that but as a small company, we have to wait and watch to see the popularity of any new model in its RH form before we can make the decision as to wheter we can offer it in left hand. In my 30 yrs of head design work, never yet has any left hand model sold more than 8% of the units it will in the RH version. Not once in 30 yrs. This figure comes from watching unit sales of models over the years at the companies I have designed for, including ours here. And it is… Read more »

Anything new regarding LH driving iron ?
I recently purchased a driver and wedges via Rosenberg in Denmark – VERY PLEASED !!!
Now i would really love a driving iron and some irons.
So sorry that you don’t do that !
I understand your sales issues, but still :O)

Tom Wishon

Sorry about that but so far, the right hand demand for the driving irons is just not nearly enough to tell us that it could be a wise investment to produce the model in left hand. And yes, it is tragic that there is no other way around this problem. But I am pleased that you are working with Thomas in Denmark for your fitting needs !

Tom this design literally hits it straight out of the park! From the minute we saw the design we knew it was going to be a great head, little did we know how much it was going to absolutely blow the competition away! We tested this head yesterday against the Taylormade UDI and callaway Apex UT which was 1degree stronger, with the identical shaft using fitting club conex fittings and the 591 DHI out performed both other heads by an average of 25 yards! This head is amazingly foregiving unlike the competition which both the TM and Callaway if you… Read more »

Tom Wishon

thanks very much for sharing your experience with the new 590 driving irons. interesting point is that because the #2, 3 and 4 of the 590DIH are all under 25* loft, that means the scorelines do NOT have to conform to the 2010 USGA groove rule change. That rule change specifically has a cut off of 25* loft for having to subscribe to the new groove radius and groove area edicts in that 2010 rule change. Thanks so much !!!


When will the driving irons be available for shipping to South Africa.

Tom Wishon

The new 590DIH driving irons are now in stock and we are filling back orders for these clubheads presently.


Tom, I really like the design of the HDI irons. I much prefer the look of an iron than a wood type hybrid. Especially on par 3’s. I know that it’s a thought process thing with me, but, I roll my wrists through the impact zone better with an iron. I practice and play with wd type hybrids trying to get that same feeling, but, haven’t perfected that yet. If the HDI’s work like I believe they will for me, I can devote that extra practice time to the short game (much needed). Hope that the HDI’s are released soon:)… Read more »

Tom Wishon

ORAN Thanks very much for your comments and for your patience with us in the eventual delivery of the 590DIH driving irons. Sometimes it does happen with a brand new model there can be delays because the factory has never manufactured the head in production. Each new head model can bring little nuances with it to the production process that the factory has to get used to because they have never produced it before. I did design these driving irons to be a more iron type hybrid for players who just never liked the conventional hybrid design that can look… Read more »
