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)

As this is SL done right I hope to join those who play this set. The concept is great for tall players without super long arms too as your wedges don’t get to back hurting short. I am just a little worried about the clubhead weight with a 38.5 inch long shaft in the irons, I don’t mind the swingweights in the high D but would a lot of grip end weight be needed to achieve that with a 95gr shaft like the Steelfiber i95?

Quinten At 38.5″ for the single length, even with a very light shaft the swingweight/headweight feel would be heavy. Whether it would be too heavy for your playing needs is something you can only find out if you build ONE of the irons at that length, with the shaft and grip you prefer to play. If it is possible to still be reasonably comfortable over the ball with a shorter length than that, you should try to do that. You did not say how long your current irons are in relation to standard length. But even if you used a… Read more »

Thank you Tom. Many years ago you gave me some great advice on how to build a set with an 8 iron being the shortest at 38″, it involved a lot of drilling in the clubheads:) But you also warned me for the challanges and told me about the single length concept you were working on. It’s great to se those single length Wishon sets now are a reality. I’ll find a fitter who wants to start with one club.

An update. I played the original design from when it was first introduced until the introduction of the EQ1-NX, so what, about 6 years? Still going strong. The EQ1-NX remains a strong upgrade from the original model. More forgiving, about the same distance, etc. I had taken out the original set’s 4-iron because I was slowing down (I’m 63) and my 8-iron swing speed is only 84mph. But with the new set I went with the 4-Hybrid (36.5″–same as the rest of the set) and I have to say I’m pleased. My fitter ensured I chose the best graphite shaft… Read more »

Many thanks for taking the time to update us on your continued progress with the single length irons. Though I did have to laugh a little bit when you said you “only” have an 8 iron swing speed of 84mph. That’s pretty stout to be honest with you!! You are aging very well I would say!! Unlike some of us (71) who have dipped below 80 with the iron speed!! HA!
Thanks,

Hi Tom, Wondering why it is that you use a 454g tip-weight when frequency analysing shafts. Some companies use a 205g tip-weight, which is about the weight of a driver`s head. Others use weights between 225g and 300g, which would be more in the range of the iron headweights. Even the head of a putter is less than 454g. So, why this particular weight? Thanks. Gary E.

GARY IN doing our shaft analysis, we are taking frequency measurements all the way from 41″ up from the tip, down to 11″ up from the tip, at 5″ increments along the way. We do this many measurements along the full length of the shaft so we can see the full length stiffness profile of each shaft from butt to tip. Once you get down to where there is only 21″, 16″ and 11″ of shaft sticking out from the front of the clamp of the analyzer, with a 205g tip weight the frequency is so high the machine cannot… Read more »

Reply to  Kevin

KEVIN Removing weight from a clubhead is almost impossible, depending on the head model/construction and the clubmaker’s skill and equipment. Technically on irons it is possible to grind/polish weight off the head, most typically off the sole where there is more metal. Even with the hollow construction of the EQ1 irons, there is enough metal on the sole to remove quite a bit of headweight. BUT – this requires refinishing the heads by grinding and polishing over a series of different sanders/grinders/buffing wheels which is something very, very few clubmakers ever are called upon to do so they do not… Read more »

Yes, if you did go with a 100-105g shaft that you like, that should bring the swt down by around 2 points, then if you could still feel comfortable with the irons at 37.25″ (1/4″ is not much when it comes to how you feel with the length over the ball), that would get you another point. 3 points down should make a difference in the head feel during your swing.

As with everyone of our iron and wedge models, the bore diam is 0.370 for parallel tip iron shafts. I doubt I will ever design a taper tip bore because there are just so many more shaft options for custom fitting purposes that are only made with a 0.370″ parallel tip.

JOHN If the irons are being made to a std 8 iron length of 36.5, there is no way the swingweight should be as high as D5. At 36.5″ the only possible way the swt could be that high is if you are using an extremely light grip, such as one that is lighter than 40grams. I am NOT a fan of using weight in the grip to trick a swingweight scale. Doing that adds weight to the TOTAL WEIGHT of the club, making it heavier. And you still have the same weight in the head. So to get rid… Read more »

TRENT No, we have always used the same exact shaft in each single length iron. Using different shafts is wrong to me because the goal of a single length set is to make EVERY IRON have the same exact playing and swinging characteristics with the ONLY DIFFERENCE to be the loft change. The whole reason single length even exists is to follow the technical belief that if every iron is identical, then every iron can swing exactly the same way to help the golfer achieve better shot consistency. Changing anything except the loft violates that concept of each iron having… Read more »

TRENT from the year single length irons first appeared (1986) until their rebirth in 2016, pretty much every single length set was based on a 6 iron length. The problem with that is a 6 iron length makes the wedges too long for the vast majority of golfers, causing them to hit the wedges too far in relation to what they are used to and what they need. I chose a BASELINE length of an 8 iron because this not only makes the wedges play as they should, but it also offers the golfer a higher level of shot consistency/ability… Read more »

Do keep in mind that when it comes to shafts and especially shafts in irons, once you find a shaft that performs well and with which you have no complaints, the chance of finding a new shaft that would offer a remarkable improvement in performance is very small. Iron shafts tend to be much more important for the contribution of their weight… Read more »

Carlos Every iron and wedge head in the EQ1 iron set is designed to be 275 grams, so they all can be built to the same length as a standard 8 iron of 36.5″.

Carlos I am sorry but it is just not possible to predict exactly what hosel weight you would need. There are so many possible variables to affect this – +/- tolerances of normal manufacturing on the head weight being the major one. You need to invest in a swingweight scale if you do not have one. Then you need to spend some time hitting other wedges that have the same length as what you want to build in this wedge until you find one that has the right balance of head weight feel to your swing tempo and timing.

JAAP Your clubfitter should have carefully measured your clubhead speed and from that, determined what would be the lowest loft IRON that you still can maintain adequate clubhead speed to be able to get the ball up enough to fly and carry a normal distance. When you see the lower loft irons of an 8 iron length single length set fly low and not carry too far, that is definitely an indication that you should have the hybrid version of that iron head number instead of the iron. Most people who normally hit their 8 iron under 140 yds should… Read more »

Colton Diamond Golf can bend the lie angles to be on these specs you listed. You just need to be very specific for what lie in actual degrees plus fraction that you need. If you say “bend 0.5* flat” then they would take that to mean 0.5* flatter than the original spec for the head in the design. It is always best to actually state the full degree + fraction when requesting a lie bend – such as “I need the 5 iron to be 62.5* lie”, for example. But they cannot alter the head weight. The head weight is… Read more »
