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, I have now adjusted the swing weight of 2 of the 5 sets of EQ1 I have currently built. I dropped the SW from D3.5 down to D0.5. Wow what a difference. Both clients immediately fell in love with the new feel even though the Sterling irons they were playing were all D3. The sterling irons felt and acted lighter with the superlite shafts but as soon as I dropped the EQs down they felt the same! It was like two totally different sets of irons. Both clients were amazed! Both were single digit handicap players. Heck, I was… Read more »

Tom, I’ve been playing your 555’s since they came out along with PCF micro tour wedges. I am going to hit the new EQ1-NX irons with Moe H. here in Maryland very soon and would like to get a set. My challenge is putting the best shaft in that fits my swing and knowing where to begin. My 555 have the steelfiber i95 R flex ‘hardstepped’ to play between R and S. My KZG blades (I sometimes play that Moe also built me) have DG 100 S shafts. This past week I did the Mizuno 3D shaft optimizer and the… Read more »

In steel the closest pattern we have to any of these tip stiff good player steel shafts you list would be the S2S Stepless. It is a 120g raw weight shaft so that puts it reasonably close to most of the shafts you list but slightly lighter. It is also a tip stiff design but do be aware that some of these shafts you list are a little more tip stiff than the S2S Stepless. Whichever of these shafts you like a lot and have never had any issues with will perform just fine in the EQ1’s.

Thanks for all you valuable advice. Can one fit variable length shafts to the Sterling heads?

Johan, it is not possible to build the EQ1 irons to have the normal incremental length differences between each club. To do that would require the headweights to be ordained at 7g increments between each head. The EQ1 are designed as a single length set only which means their headweights are all the same at 275g with the usual +/- tolerance.

Hi Tom! Any thoughts on a professional long driver playing these (or the Sterlings)? As somebody who rarely gets on the course or practices his normal golf swing much anymore, I am very intrigued by the single length concept! Seems like it would be much easier to keep my game in shape. I don’t know what my swing speed looks like with my irons these days, but my driver swing speed is around 140 MPH, ball speed around 210 MPH. Do you think these will work for me?

I am in Rochester, NY, in case that affects your recommendation. Thanks!

MIKEY The concept of single length irons is viable for any golfer as evidenced by deChambeau’s use of single length in his whole high level career in the game. With very veteran good players who’ve been used to conventional irons their whole lives it comes down to whether the player, a) gets fit properly and, b) whether the player is committed to taking the time necessary to evaluate distances and distance gaps, make any loft adjustments that may be necessary, and c) get used to now having wedges that will be at least an inch Longer than what you have… Read more »

Tom, thank you for the response. As somebody who swings 48″ long clubs 95% of the time, a 35″ wedge feels like a child’s toy in my hands, so I have no particular affinity for the variable length irons I’ve been playing with my whole life. Quite the opposite, actually — there’s a reason I switched to long drive! I think I will really enjoy hitting a wedges that feel like 7 irons.

I am looking forward to the fitting and gapping process as I begin my single length journey. Thanks for the advice, Tom! I really appreciate it.

Tom, I have now built 4 sets of the eq’s and just ordered my 5th set today. One of my guys is hitting the 6 iron 200-206 yds on my gc2 in the studio but can only get 205-210 out of the 5 iron. Would you suggest increasing the loft on the 5 or decreasing? I am torn with what would be the correct move. I feel like the 5 is launching a little low and raising the loft might increase his carry. Am I wrong?

Also a big gap between the 8 & 9.

Steve Thanks for the input so I could have a chance to offer some assistance. Since you say the #5 iron launch angle seems a little low, try increasing the loft +2* and see what happens. More than likely the biggest reason the shot pattern is lower on the 5 and the carry is not a full club over the 6 is because the golfer does not have quite enough clubhead speed to make the 24* loft at the short single length be able to elevate the shot up high enough to achieve a full club carry over the 6.… Read more »

Reply to  Steve poe

Steve You cannot aim for any specific dynamic loft at impact because dynamic loft is a product of the golfer’s ball position + angle of attack + what the loft is of the club being hit. It is kind of set in stone so to speak by the golfer’s swing tendencies. What you look for is the distance gap between the two clubs. If the gap is too little, you first would add some loft to the 5 iron so you can get this golfer’s shot height up higher to see if that helps get him more carry distance from… Read more »

STEVE: I might be misunderstanding what you said – did you say you have at times put two 9g or two 6g tungsten weights into the weight bore of our iron heads? Keep in mind that the weight bore is 15mm deep (+/-1mm). The 9g tungsten weight is 13mm long, the 6g tungsten weight is 9mm long. So if you put two weights stacked on top of each other down there, your shafting depth will be reduced. And you NEVER want to have the shafting depth for a 0.370″ parallel tip iron shaft to be less than 1 inch –… Read more »

Tom, when you select shafts for single length irons I’m not sure of which shafts to obtain? I want to get shafts for a set using 8 iron lengths for the 6I – AW (6 clubs).

  • Do I use six 8 iron shafts with 3″ tip trimmed on them all and then butt trim them all to 8I length?
  • Or do I use six different shafts (S2S steel for example) using the 6I, 7I, 8I, 9I, PW & AW shafts tip trimmed differently per the chart and then butt trim them all to 8 iron length?? Thanks

JOHN Whenever you are building a single length set of irons, think of it from an assembly standpoint as building a whole set of 8 irons. So if you are using a parallel tip iron shaft model you would tip trim every shaft the same as per the shaft maker’s instructions for what the 8 iron tip trim would be. If you would be using a taper tip shaft model you would buy the same raw length shaft for each iron that the shaft maker says is the right raw length for an 8 iron. So if the company’s tip… Read more »

Reply to  David Eikner

If you choose to play the single length irons on the basis of a 7 iron length (37″) then you tip trim all shafts as per what the instructions say for a 7 iron installation. Then for the irons at 8 iron length (36.5″), you trim all the shafts as per the instructions for an 8 iron installation. The key is that since all the irons are the same length, the shafts all have to be trimmed the same identical way.

Admin

Reply to  J. Kaiser

J KAiser Lie angle is directly related to club length and the golfer’s set up position as well as their position through impact. In a conventional incremental lengths set, because each iron is a different length, the golfer sets up a little different with each club and also has a little different posture/spine angle through impact. Hence the need to have a different lie on each iron of different length. When all irons are the same length, they really should be the same lie because you are using the same exact stance, set up, posture, spine angle and hand position… Read more »

ROB Sorry but that is a bit of a reach for me to agree with because when shafts are shorter as they are in a single length iron set, they are pretty stiff and even if what Cobra say is true about golfer’s consciously swinging lower loft single length clubs faster, it would not be more than 1-2 mph faster because the clubs are all the same length. Angular acceleration characteristics would prevent any conscious increase in golfer effort from bringing about more than a very small increase in speed. And an increase of 1, 2, 3, even 5mph just… Read more »

When fitting a set of SL irons or even any irons a dynamic lie angle test could be performed by the club fitter and builder for each iron individually. So each iron will have a lie angle that gives you the best performance and that may be a bit different from iron to iron.

Cobra’s approach is again a one size fit all approach with a lot of assumptions. Wishon clubs are designed to be custom fit one club at a time so no assumptions are made.

Lie angles can be changed. You don’t want to have an open or closed face. Offset is 2 degrees throughout the set. The heads don’t look like GI or SGI. As Tom notes, you work the ball with solid contact, adjusting the angles (path, face) to curve the ball. Perimeter weighting helps with off-center hits, but does not hold back moving the ball. I was a mid-single-digit player when I switched to Sterlings almost 4 years ago. I did it because iron play was the most inconsistent aspect of my game. It isn’t anymore. My set consists of 5-SW, and… Read more »

What you propose with the 575 long irons being part of the bag with single length irons can be done. The main thing you would have to do is to spend some time with the #5 iron in the single length set and the #3, 4 irons from the conventional lengths 575 set to determine what the distance gap will be between each of these irons and then from what you find in hitting them, to figure out whether you need to tweak the lofts of any of these three clubs to make the distance gaps be proper.

Question about the high cor 5-7 irons. With the sterlings I know the thinner variable thickness faces were heat treated which made the irons more difficult to bend than the 8-lw. Is this the same with the new model?
