SINGLE LENGTH IRONS

 

Wishon’s new single length iron design concept EQ1-NX offers same length and high COR low loft iron characteristics while adding many new performance enhancing features to mark a definite step forward in game improvement iron design.



Features:

    • Enabled by the new 2-piece hollow body design, the Center of Gravity moves progressively through the set from lowest and most rear located on the #5 iron to highest and most forward located on the GW and SW to achieve more consistent shot shape and shot height for each iron in the set
    • The hollow body design throughout the set increases the MOI of each head by removing all mass from the inside of the head to be distributed all around the CG.  The hollow body construction also enables the CG progression and uniform impact sound between the high COR and conventional COR heads in the set 
    • Low number irons are better matched with their loft to CG position to achieve preferred shot shape/height and allow a wider range of players to be able to effectively hit the #5 and 6 irons to fly and carry with proper distance gaps
    • Traditional GW and SW profile shapes are combined with milled faces and a custom sole grind make the wedges a great choice even if they were standalone wedges and not part of the single length design 
    • 275g head weight with hosel weight bore allows assembly to any single length between 35.5” and 37.5” while still being able to achieve a reasonable range of swingweight/MOI (depending on shaft weight and grip weight)
    • Available in RH in #5-9, PW, GW, SW, LW. Available in LH in #5-9, PW, GW, SW,

Greetings Tom. I was wondering if it would be possible to make irons that have the loft stamped on them instead of the number – EG 24 (degrees) vs 5 (iron)? Given that the industry is constantly changing what the loft of any given club is, it makes more sense to me to use the loft. What a 3 iron was 10 years ago is now a 5 iron in terms of loft. So, for someone to say “I’ll hit the 5 iron,” is totally contingent upon the manufacturer and the year in which the clubs were made. But a… Read more »

MARKUS I have been one of the most outspoken people against this steady decrease in loft of 8* or more for the majority of the irons in a set over the past many years. But I have also seen a company or two that tried to do exactly what you suggest to put the loft number on each head instead of a number and in each case the practice failed miserably and caused the immediate demise of the sales of the set. Last one to do it was the company that had bought the Ben Hogan brand a few years… Read more »

Thanks for the reply, Tom.

It’s unfortunate that people are so lazy as to not know the loft of their clubs. Moreover, that the manufacturers rely and prey upon that ignorance to create the “best new thing”. Hit your 5 iron further than ever. It’s a 1* club…but, shhhhh, who’s telling?

Bummer about the 4 iron, as I can hit one just fine and would prefer that over a hybrid.

On a different note, what’s the bounce on your sand wedge?

Thanks,

Hi Tom, I’d like to build a 4-club “wedge set” using EQ1-NX wedge club heads (PW to LW) but at a standard overall length of 35.5”. Obviously, they need to be a playable SW/MOI using existing 9g weight port. Using an additional 4g tip weight would be the maximum 13g hosel weight, as I recall from one of your previous fitting articles. What’s the downside if I exceed 13g weight port and tip weight total? I’m not shooting for a MOI-matched “wedge set” but I’d rather like having different MOIs with SW club being slightly heaviest. Kinda like what’s in… Read more »

BILL GREAT to hear from you again!!! Going with a tip weight on top of using a 9g weight in the hosel weight bore is completely ok. The effect of having a total of 13g in the heel side of the heads will SLIGHTLY move the center of gravity toward the heel side of the face, but not more than about 1/8″ to 3/16″. That’s not enough of a shift of the CG to cause any performance problems because you are doing this on wedges that have a lot of loft. In fact, there are tip weights up to as… Read more »

DON the vast majority of iron models I have designed have been 1.5″, not 1.25″. 1.25″ is a rarity in my design world. And hosel length is hosel length and has nothing to do with BBTG, BBTG comes in when you factor in the bore depth with the hosel length and the toe to heel sole radius. But I have kept with a 250mm radius from toe to heel on the sole in my design work so the only way one iron model’s hosel can stick up longer than another would be from the hosel length.

I have been down a rabbit trail on SL irons for a few months now and am still a bit unclear on how the shafting works. It seems like other manufacturers have made their clubs with different shafts (among other differences) to aid in achieving the desired ball flight particularly in the lower lofted end of the bag. Is that typical of all SL designs, or are the EQ1-NX irons designed to have an identical shaft throughout the set? I was able to get a pair of EQ1-NX demos rented and found the everything about them to be generally positive,… Read more »

Bryan Happy to help you get out of the rabbit hole. It’s no fun being where you don’t know what’s up or down! First of all, the concept of single length is to make each iron ABSOLUTELY IDENTICAL to every other iron in every spec, except for loft. Incremental length irons change in total weight, balance point, assembled club MOI, and of course, length. With everything identical in every way except for loft, the logic says the golfer could find it easier to become more consistent since every club really will swing the same. Second, iron shafts don’t even come… Read more »

Nice of you to provide the level of engagement and clarity you do here. The SL concept is extremely interesting to me because any reduction in variables can’t help but improve consistency which is something my golf game really needs.

I am sorry about the lack of availability of left hand models but with 8% of the golfers worldwide playing left handed, it’s tough to tool up every model both ways. Regarding your question, I am going to bet that the main reason you find anything longer and lower lofted than your 7 iron to be subject to consistency issues is because of the lower loft of the 6 iron and the other lower loft clubs. All lofts below 31-32*, which is about the average loft for a 7 iron these… Read more »

Adding to what Tom posted, two thoughts from a long-time (8 years) single-length player: The first time I hit the previous version (Sterling) was when I owned the set. And I’m glad I did it that way. Single-length clubs are easy to quit on at first because of two strange things. First, the low-lofted irons feel absurdly short. Second, the wedges seem incredibly long. But after a very brief period of time, you get used to the real issue: that all of your irons are the same length. It no longer feels at all odd to have a really long… Read more »

I’ve tried the 771 & 565 at a demo fitting session and was pleasantly surprised how good and powerful both appeared.

Certainly the 771 launched higher than I’m used to even tho my own clubs have the same loft.

Would the COR etc be similar?

Reply to  Garry

Garry By intent in the design, only the #5, 6, 7 irons of the EQ1 irons are high strength steel face/higher COR face designs. The 8 to wedges are conventional COR design. Reason for this is that in a single length set in which all irons are 8 iron length, the low loft irons need a little help to get the ball to fly and carry farther so there can be a full club difference in carry distance between each of the low loft irons. Using a higher COR face helps offset this tendency of single length low loft irons,… Read more »

Long-time user here, first with the Sterlings and later the EQ1-NX. Three quick thoughts: First, no manufacturer should announce a new model too soon. It can shut down sales of current inventory while users hold off buying decisions, choking revenues and even cash flow. See Osbourne Computing for a famous example. Second, I cannot imagine what performance improvements would be available. The EQ1-NX was an improvement over the Sterlings, but not a radical one. (Reduced offset and greater forgiveness were the two I noticed most.) But Tom’s the genius here, not me. Finally, the idea that single-length irons being associated… Read more »

Keep your grips fresh and consider having the irons re-grooved after several years of use. But this last one comes with two caveats.

Hey Tom,

Why did you go with 5-degree gaps in the wedges and higher lofted irons then 4-degree gaps in the lower lofted irons?

Intuitively I would think I would want the wedges to be closer in gaping and the lower lofted irons to be further in gapping… especially since it’s not uncommon for people to have insignificant gaps between lower lofted clubs when using one length

Admin

Reply to  trent

Trent In an absolute perfect world where EVERY golfer has a completely open mind, the best situation for loft gaps would be to use 5* increments between the low loft irons and then reduce that slightly as loft increases down to the wedges. The lower the loft, the harder it is to elevate the shot high enough to achieve full complete carry distance. The only golfers who get the same distance gap between their low loft irons vs high loft irons when the loft gap is the same throughout the set are players with very high clubhead speeds. For average… Read more »

JON I play a very large oversize grip on all my clubs including all of the EQ1 single length irons. The grip weighs 76g so of course it drops the swingweight substantially. TO counteract that to prevent the clubs from feeling way too head heavy I play the swingweight of my clubs at C5. Relatively speaking, a C5 swingweight with a 76g grip ends up with about the same head weight feel as would a D1-D2 swingweight on clubs that had a normal 50-52g grip.

What would the approximate swing weight be for a set of EQ1-NX irons at 37.5″ and a 65.5g grip at these different shaft weights:

WES Shaft weight is not the only factor controlling swingweight in a set. The shaft’s weight distribution, whether it is a tip heavy or butt heavy design, is another weight factor in shafts that can have a definite effect on the swingweight. In general though, the swingweight changes by 1 point per each change in shaft weight of 6 to 7 grams. So if you have a club at D2 with a 130g shaft, when you drop the shaft weight by 6-7 grams, you drop the swingweight by 1. Hence if you reshaft the 130g club that is D2 with… Read more »

Any clubmaker would be able to change any of the specifications of the irons. What you need to be cognizant of in whether the irons fit you would be the length, the lie angles, the shaft model/weight/flex, the grip type and size, the swingweight. Any experienced clubmaker should be able to analyze you and address those things.

As they say in London at Underground stations, “Mind the Gap!”

You should also pay attention to the carry distances you get with each club, considering whether or not you need to tweak any lofts to maintain proper gapping between clubs.

Otherwise, I echo Tom’s point, and pile on by saying it is critical to have any set of irons properly fitted to you and your game (along the parameters he mentioned).

ROB 431 stainless is almost never, ever plated because it is almost always passivation treated at the factories to fully prevent any possibility of rust forming from outside pollutants that may come in contact with the heads. Thus the conventional mode of finishing any 431 head is through polishing, which can be done in different finishes including mirror polish. So the shiny finish is simply polishing of the surface. All mirror polished stainless heads will dull out over time, a condition which most golfers just live with when it happens. However, there are a handful of companies in the US… Read more »

I read and have been told numerous times that an incorrect shaft flex could lead to too much (or too little) lead bending, resulting in more slicing (or hooking). Is any of this true?

TAY You have to be careful in making the assumption that duplicating the swingweight of the HM wedge in your other irons. You did not say what the length and swingweight of the HM wedge is, but I must assume that it would be higher than normal because the headweight of the HM AW is heavier than the head weight of the EQ1 at its 36.75″ length. The headweight of the HM AW should be around 284g and the length is probably shorter than the length of your EQ irons, bu I do not know if you added any weight… Read more »
