What They’re Saying About the 870Ti Irons

Donald TOctober 5, 2012
You’ve seen the advert that says “It does exactly what it says in the box” well this head does exactly what it says it Tom’s video, above. Super distance, I used one club less than my previous set, great launch angle and boy does the ball stop on the green. Superb head. Thanks Tom.    http://1.gravatar.com/avatar/77df55638fbcf00d125dbe4092bb188a?s=56&d=http%3A%2F%2F1.gravatar.com%2Favatar%2Fad516503a11cd5ca435acc9bb6523536%3Fs%3D56&r=G

These are the best irons that I have ever played. My game is more consistant and shots are straighter than with any club that I have ever played. Does not hurt that they are great looking

Built my friend a set of 870,s now I am in trouble he went from shooting in the low 90′s to high 70,s and beats me every now an then, last time I told him becarefull I will built me a set.

Voor de gemiddelde golfer is de 870Ti de beste keus. De eigenschappen van dit ijzer zijn zo superieur dat elke golfen eenvoudig lijkt. De consiotentie en vergevingsgezindheid die dit ijzer geeft vind u in geen enkel ander ontwerp. Voor mij is dit het best verkopende ijzer van de afgelopen jaren.

The 870 Ti irons are a great Wishon design. With the higher MOI from increased weight in the toe and heel area and beta ti face design for increased distance is a great fit for several golfers who have lost distance due to loss of flexability or suffer from bad backs or other injuries that prevent game enjoyment. These irons will give back lost distance and bring enjoyment back into playing the game.

Very well performing club. The sound is somehow clicky, but you get used to it and then you know when you hit it dead center.
Playing this head is like cheating. Off center hits don’t hurt because the ball still goes straight and long. Highly recommended for slow swing speeds, but works for all others as well.

I’ve played the 870 for several years now and my game has improved. A very forgiving and solid iron head. No reason to change.
BirgirOctober 15, 2012
I tell my customers these are the most forgiving heads on the market. If they want their bad shots to turn out better and get a bit more distance and height, these are the heads. Use these heads personally and notice the same results as my customers.. it’s increble how good shots are that are hit way off center!
Also a great feature of the 870Ti’s is that they have a very traditional look from address for a forgiving iron, little offset and not a hugely wide sole. Only noticable thing is the heads are quite large, which one gets used to VERY quickly. They have a very distinct sound/feel to them. A bit of a click from the thin titanium face.

Bottom line – The longest and most forgiving heads available(and in my opinion they look great)!

the 870s are awesome.About club longer for me.easy to hit,look great, limited offset.
Chad AbelNovember 27, 2013
Was not convinced based on the catalog description, but after fitting several golfers to this design I am sold. These heads are gorgeous, forgiving (an understatement) and get the ball up quickly.
That signature “click” has become very satisfying feedback for several customers. Well done Tom!

I remember the Penick-Plus Ti faced irons you designed back in the 1990s or early 2000s. How do the new 870 Ti designs compare?
Tom WishonDecember 12, 2013
Yes for sure, I remember the Penick Ti face irons you refer to. I’ll be totally honest. Back then in the mid 90s when I did this design, I only thought of using the titanium face to be able to increase the weight around the perimeter of the face, so as to increase the MOI of the head and offer a little better off center hit performance. Taking all that face area and putting a very light Ti face in there allowed us to put more weight around the perimeter of the head, which did definitely increase the MOI.
But back then we were ignorant to the possibility of using the titanium to increase the COR of the face to increase ball speed and distance. For one, no one in the industry in the 94-95 time period was aware of COR – the USGA’s rule limiting it did not even come about until 98. So we never thought that it could be possible to use the greater strength to elasticity property of titanium to increase the COR and distance of the shot.
For me, this realization that it could be possible to increase the COR of the face of an IRON came about in 2000. Since that time I have been able to design three other irons with thin face/high strength to elasticity materials to increase the COR and distance.
So the BIG thing with the 870TI vs the old Penick irons is that the 870s do definitely have a tested and verified COR of 0.830 – right at the limit of the rules. The Ti face in the Penick irons was made thicker which effectively stopped the face from having a COR that was any higher than what had been the norm with all previous thick face cast stainless irons. Add to the higher COR of the 870 the fact that the variable thickness design of the thin TI face also GREATLY improves off center hit distance and you have an additional plus for the 870 over what the Penick Ti face iron had.

I was recently fitted for a set of 870ti, what Iam wondering is if you can answer two questions.
1. Are the 870ti today the same as the 870ti that came out in 2009? If so have they fallen behind in technology compared to the new advancements the majors are claiming they have found in the last couple of years ( compare the titliest Ap1 muzuno ez jpx, ping g25)
2. What is the main diff between the 870ti and the new 771csi, should I consider the newer 771 is it newer tech.
Tom WishonApril 30, 2014
Thanks so much for your interest! The 870Ti model is the same design with no changes that we introduced in 2009. I doubt seriously it has “fallen behind” in any aspect of its design technology in terms of both distance and off center hit forgiveness. Why I can say that is because when I was over in Europe giving clubfitting seminars for various European PGA organizations in the summer of 2008, I had the chance to visit the R&A’s technical department and have the final testing samples of the 870Ti irons officially tested on site for COR at the R&A. They confirmed through air cannon COR testing that the 870 did have a COR right up at the 0.830 limit imposed in both the USGA and R&A rules for ALL clubheads.
So no matter what any other company has done in the past 5 yrs in their iron designs, from a pure COR vs ball speed and distance standpoint, no other iron ever made can have a higher COR and higher ball speed than what the 870 offers. The ONLY way any other iron could hit the ball farther is if it had the same 0.830 COR AND was made with a lower loft for each head number compared to the lofts of the 870.
Off center hit wise, the variable thickness face of the 870 is a feature that allows the face to maximize face flexing to deliver less of a distance loss when the shot is hit off center. Here again, based on my testing, I just cannot imagine any other iron can achieve any better off center hit distance because I see no other irons made with a variable thickness face.
The only features that the 771CSI irons offer that go beyond what is possible with the 870′s are, 1) far greater bendability for lie or loft changes should the golfer need that in his fitting requirements. The body of the 771 is made from soft carbon steel to allow it to be bent +/-4* for loft or lie changes while the body of the 870 is made from a stainless steel alloy that is less bendable. 2) the 771 is designed with a smaller overall size and profile than the 870. I did this so players who wanted the high COR/variable thickness face design in an iron could have an option for head size. Some golfers simply prefer a little smaller size head while others prefer a larger size head. So this factor of head size is simply a “psychological” option to meet different preferences for the look of the head behind the ball.
And those are the facts. We’re quite different than any of the other golf club companies in that we do not feel compelled to bring out new models every year or every several months. Our primary approach is to offer golfers the real benefits of professional clubfitting from scratch with the most innovative head and shaft models we can create rather than to pre assemble clubs to a series of std specifications so they can be sold off the rack to golfers. As such, when fitting from scratch is a key part of the offering, a model that is well designed and performs well really never gets old. As a result, we have MANY models in our design line that we have had for several years and which maintain their popularity with the clubmakers who work with our designs in their fitting work. As long as a model remains popular, we continue to offer it. Such is the case with the 870s and several other of our models.
Thanks very much,

Thanks for you response.
Last night I went to my first fitting session and spent most of the time hitting the 870ti head with a couple of different shaft/length options. The fitter had a couple issues with the fittings holding the head in place on the differnt shafts so i was limited to trying only a few combos. He took video of my swing and then inputed some info into your software for a shaft match, but I am a little skeptical in terms of that being the final product based on the software. I thought the process would involve lie and angle setup a little more as well as more of a comprehensive or custom fit shaft option. I really only hit the 771 a couple of times but didnt compare them to the 870ti much. I am coming from Titleist 704cb forged irons which are considerably smaller and more “feely” than the 817ti and am wondering if this will be to much of drastic change goven the size difference. Should I be asking for more customization or is this the standard process. If I am going to Wishon I really want the custom options on shaft and lie etc to ensure that my swing type is matched. Next step is tomomorow apparently the fitter is making me a 7 iron with the shaft recommendation and lie angle he got from the data. I am wondering about choice between the 771 and the 870ti esxpecially coming from a 704cb almost blade type iron.

Given that you say the clubfitter used video AND was consulting our shaft software data base for shaft comparison information, I would say that the fitter you are working with is a step ahead of most who fit golfers. Those things qualify as a bit of a more thorough analysis in a fitting session. While the guts of a proper fitting will always be working with the fitter to nail down your best lengths, lofts, lies, shaft, total weight, swingweight, grip type and size, IT IS CRITICAL that the golfer like the head model that he chooses or that the fitter recommends. The performance of a different head model certainly is a key part of this, but very much so the golfer has to LIKE THE LOOK of the head when he sets it down behind the ball. Give a serious player a head model that just does not look right to him at address and it won;t matter how good all the key fitting specs are – the mental perception of a head model is very, very important. So please be sure you take enough time to really consider the long term side of living with a new head model so you can get to the point you are sure you like the look of the head along with the key fitting specs.

Tom thanks so much for responding to my inquiries. I am going to take a real hard look at the 870ti and the 771csi this evening. At the end of the night one of those heads will be making up my new set of irons. I love Wishon quality, the custom fit experience!

Hello, I was just fitted yesterday by Jacques Lavack in Winnipeg ,Mb Canada. I would just like to say that the fitting was wayyy beyond my expectations! I was there for almost 5 hrs and went through about 4 buckets of balls while we fine tuned everything from swing weight, shaft, club head styles, lie angles, basically everything that could be fitted , was. In the end I ordered the 870′s (6-sw) as well as the 919 driver and 3 hybrids. Took the 3,4,5 irons out of the bag! I can not say enough good things about the whole experience and if anyone is “on the fence” about getting fitted/buying Wishon clubs, I highly recommend it. I will come back once Jacques finishes building the clubs with some more feedback! You have a great fitter representing the Wishon name here in Winnipeg Tom!!
Tom WishonAugust 25, 2014
Thanks very much for taking the time to let us know what a great experience you had with Jacques in your recent fitting analysis. That right there is what real professional clubfitting is all about and how the most experienced fitters do conduct their sessions for golfers. And we’re so pleased to have Jacques working with us, representing our design line in his work, because I have known him for a very long time in this side of the industry and have always been impressed with his passion to do the best to help the golfers who come to him for help.
Thanks !!
