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)

Tom – On the cusp of ordering a set of EQ1 irons made to replace, but struggling with the decision on wedges at the same length. Would really prefer a set of wedges at 4* steps … i.e., 44*, 48*, 52*, & 56*. What would you suggest? Thanks

C Scott From our experience, most golfers who have never tried a single length iron set will require a few weeks to get used to the wedges at the same length as the rest of the single length irons. But once they do, they tend to not think about going back to have the wedges be shorter than the rest of the single length irons. In fact, most end up liking the wedges at single length which makes them longer than what they had in a conventional lengths set because they do not have to bend over or crouch down… Read more »

Hi Tom,
I wish you a happy New Year!
I read a previous post of yours where you describe the face treatment of irons. You mentioned that in the past iron faces were rougher because of aluminium oxide sand blasting.
Can you share how the faces of the EQ1-NX irons are treated and how the roughness compares to an 180 grit aluminium oxide sand blasting?
Many thanks and best regards Daniel

Daniel At one time, prior to the 2000s, blasting with AlOx sand was the norm. But it began to be felt by many in the clubhead production business that an AlOx blast was more dark grey than what was desired so the change began to be made to use Silicon glass beads for face blasting because it left a much lighter grey color to the blasted surface. The change thus was made ONLY for cosmetic reasons because it was felt the light grey color of the glass beads was better looking. However, AlOx leaves a more rough surface by far… Read more »

Tom I am building a set of EQX-1 Irons, Hybrid and woods using your S2S white shafts. I have run into a problem with the frequencies on trimming the iron shafts. I have trimmed 2 shafts 3 inches because of the weight of the Iron head and plan to build to 37″ length. The 6 iron weight is 276 and frequency is 294. The 8 iron weight is 277 and Frequency is 286 . I know I can trim another inch off but I do not see how that will get to a regular flex frequency? I am I missing… Read more »

GREG I have to apologize straight up and tell you that I really do not see any superior benefit to going to all the work to try to get all the frequencies of the shafts exactly the same in a single length set. That’s way too much work for whatever perceived benefit that could be. Now within a high to low range of 2-3cpm? OK, because you would not want the range to be like 4, 5, 6 from high to low if possible. For one, to really nail down the FQ for each club you would need to start… Read more »

Thanks for your reply. So my logic is to use the 287 CPM on the 6 iron then and the Highest CPM of 295 on sand wedge. Does that make sense or do I need to do it in reverse?
Thanks and have a Great new year.

Greg Yes, using the lower FQ shafts on the lower loft irons and higher FQ shafts on the higher loft irons is most definitely the way to go when you have a range of FQ in the raw shafts you bought for a set. This goes regardless if you are making a single length set or a conventional incremental length set. Having a smidge more flexibility in the lower loft irons can help some players get a little bit more launch angle than if they would have used a stiffer shaft, although in total honesty it is a very small… Read more »

Wanting to pull the shafts out of my sterlings to put in the eq set. Curious if the hosel depth and bottom of the bore to the ground are the same.

JOE BBTG is the same for both the Sterling and the EQ, however, there are always going to be +/- tolerances for the bore depth AND the hosel length. So you can never expect to pull shafts from the Sterlings and have the lengths end up all perfectly the same as they were when you install the shafts as is into the EQ1s. It should not be off by very much at all to use the same shafts because these tolerances are small but you do want to check the length for each shaft you pull when it is test… Read more »

Hi Tom,

I am considering building a set of EQ1 single length irons. Currently, I own a set of Callaway Rogue X irons which are set at stronger lofts than the EQ -1’s. I like the distances I get with the Rogue X but would you recommend I make the EQ-1s 3 degrees stronger across the board to better match up with the Rogue X lofts?

Admin

Stephen That’s a tall order to try to expect that your final distances will be the same for each number iron between the two sets when the Rogue set is conventional lengths with stronger lofts and the EQ1 set would be all single length, most typically at a 7 or 8 iron length and with higher lofts per each numbered iron. You have two very distinctive and significant variables going between the two sets that will make it almost impossible to guess on what lofts with the EQ1 could give you the same distances for each numbered iron. The best… Read more »

Hi Tom,
I looking at getting fit for single length iron EQ1 set in January. I currently use Vokey wedges 50, 54, 58. Can I still use those if I reshaft them to single length set or do you suggest I get gap and sand wedge with new set. Also what are your suggestions to LW?

Reply to  Russell Kelly

RUSS Other wedges that are designed and made to be conventional wedge lengths cannot be adapted for use with a single length set of irons. The reason is because for example, the wedges in the EQ1 set are the same headweight as all of the other irons in the set at 275 grams. That weight allows the EQ1 irons and wedges to be made the same length, usually something close to an 8 iron length of 36.5″, and end up with the same identical specs for every other spec. Custom fitting determines if that needs to be a little longer… Read more »

The tooling die for the LW is being cut as we speak. That’s the good news. Now the bad news is because of the HUGE increase in demand for golf equipment during the Covid summer, every clubhead production factory on the planet is way behind in their production lead times. So even if the die is finished tomorrow, with this big push against the lead times happening, we would not see the LW heads in stock until believe it or not, late next spring at the very best. But it is coming!!

RUSS It’s interesting and it’s also too bad that some of the clubmakers are so traditional in their thinking that they cannot wrap their heads around the concept of single length irons being completely ok and viable.

Because all of the clubmakers are independent and not tied to us formally in anyway, we have no control over telling anyone what to fit and build. If you cannot find someone to work with you in your immediate… Read more »

Couldn’t handle the lower (D1.5) swing weight–a function of my personal build, not the clubs. So I swapped out the Pure grips in favor of the lighter Winn Excel grips. (My personal favorite anyway.) This bumped the clubs to D3 and they feel right to me. I’m no longer losing them at the top, cutting short my turn, etc. I’m still sorting things out on the course, but I think these clubs are a 1/2-club longer in carry distance over my Sterlings. Not sure if this is a function of the club head or the lighter shaft (graphite now over… Read more »

When I had this set built, I switched to a lighter shaft as well, going from a 110g steel shaft to an 86g graphite shaft. I also went from a D3 swing weight to D1.5. Lighter gross weight, lighter swing weight. What could go wrong? Plenty, and nothing to do with the EQ1-NX, except one little thing I’ll mention below. During the round, I was getting mixed results.

Hi Tom, your new Q1-NX irons hybrids and fairway woods are working out better than expected. I spine, pure, profile and frequency match all of the shafts to the designated heads and have found them to be extremely consistent in MOI, and distance gap between every club. From the feedback from my customers, they are all extremely pleased with the solid feel and ease of playability, one single digit player, who is 6’8″ tall and player Mizuno for years, said ” they are the best clubs I have ever played” . Thank you for such a good product!

Neil Experience with the single length concept and designs is showing us that any level of player could use them but they tend to show their ability to help golfers more in the hands of players from say, 6-7 hdcp on up. They tend to show their performance best for players who have been struggling with consistency with the irons so that’s why a really low hdcp player might not jump on these right away since he’s already pretty consistent with the irons. But it’s why average players tend to get more immediate benefit. A really important part of single… Read more »

Okay, after two driving range sessions, I went into the simulator to check for gapping, willing to adjust each club stronger or weaker as needed. It wasn’t needed. The gaps were good. Carry distances for a decent strike: 5I – 199 6I – 186 7I – 173 8I – 162 9I – 151 PW – 139 GW – 128 SW – Not taken (awaiting delivery) The carry distances are not valid–you can’t take them to the golf course. But they’re reliable–they predict good gapping. I’ll be more precise with distances with experience. These numbers are similar to my Sterlings, but… Read more »

Tom, Hope you’re doing well and thanks again for all your input on this chain. I was wondering if you thought there was any chance that the EQ irons could be creating more shaft droop than the sterling irons did? It appears since the head is slightly longer than the sterling and they appear to be waited a little more in the toe of the club that when I put the same Wishon superlite stiff shafts in the EQs that we used in the sterling irons, I seem to be getting a lot more toe down look at impact and… Read more »

I think that is possible given the increased blade length of the EQ1 irons. We did not see this in hit testing though we were not looking for it either because it never dawned on us to check that out. When we do lies for the hit testing we know what lies to bend before the hitting takes place so no actual lie checking or fitting was done in the testing. And none of the hit testers said anything about detecting any change in the orientation of the iron heads through the ground and impact. I would do the vertical… Read more »

Will the 1 weaker degree on the loft 8-5 irons relate in some distance loss compared to the sterlings? Also, does these clubs offer more forgiveness for toe hits than the sterlings?

Reply to  Leon

LEON It depends on the golfer and their swing characteristics as to whether the +1* higher loft on the 5 to 8 irons will drop distance. In general, the higher the clubhead speed and the more consistent the golfer swings, the more chance there is that the +1* loft increase will drop distance by a small amount. But as the clubhead speed is higher and the golfer has a few swing challenges, in many cases the higher loft can help get the ball up more to stay in the air longer to generate either the same or even a little… Read more »

I just got fitted for the EQ1-NX irons last week. During the fitting I was initially catching it on the toe, but it was due to something in my stance. So I corrected that and off I went! But here’s the thing: I couldn’t tell I was hitting it out on the toe, neither from the feel nor the performance on the simulator. I only knew because I checked the contact tape on the clubface after each strike. I agree with Tom that there isn’t a huge difference from the Sterlings, but it’s there and it’s real.

Hi Tom,
sorry if this is a silly question but i’ve been asked it and want to confirm before replying.
the information for these irons states 5i to SW can be assembled to any single length from 35.5 to 37.5 inches which i assume to be PW to 6i length. Is this correct?
I also assume this would also apply to the eq1-nx hybrids if they were in the set?

Reply to  rob

ROB The range in length that the EQ1 irons can be made does of course depend on the weight of the shaft and weight of the grip. If the player insists on a heavier shaft such as 110-130g it would not be possible to hit normal swingweight ranges at 37.5″. And if they used a very light graphite shaft such as 55-65g it would not be possible to reach normal swingweight ranges at 35.5″. But assuming that a player would use a lighter shaft at a longer length, 37.5 is possible with a 55, 60, 65, 70 g shaft. 35.5… Read more »

Standard 8-iron length (36.5″) throughout the set. Freq match and spine match on the shafts. On the sim, hit the 7-iron ~180yds carry at 90 mph swing speed. My normal toe misses still carried well.

Steve The EQ irons are made from 431 annealed stainless steel with no plating over the top so they will slightly dull out and slightly darken from their factory new mirror polish finish. All stainless polished irons will do that. Face wise you can re sandblast the face scoreline area with no fear of doing anything wrong to the clubhead and that can make for a little brighter look, depending on the blast media used to sand blast the face. Best for brightening up the face area is to blast with silicon glass beads. You should be able to find… Read more »
