Titleist answers questions about the 716 AP1 irons

Published

on

When it comes to irons, Titleist is historically known for tour-inspired models such its MB, CB and AP2 irons. With its 716 iron launch, however, more attention has shifted to the company’s larger, more-forgiving AP1 irons — and for good reason. They’re arguably the most improved irons in the company’s new line.

“With an impressive boost in distance, the uber-forgiving 716 AP1 irons can compete against any model in their class,” we wrote in our review.” Their design boasts an attention to detail that will give them the nod with discerning golfers.”

Our editor, Zak Kozuchowski, spoke with two members of Titleist’s top brass — Vice President of Marketing, Chris McGinley, and Vice President of R&D, Dan Stone — to discuss the changes made to the new irons.

Why were the changes made, and what do they mean for game-improvement iron shoppers? You’ll learn that and more in the Q&A below.


 

ZK: When we talked to top club fitters about AP1 irons of the past, they usually described them as “forgiving” or “very consistent,” but never “long.” Why did Titleist decide to focus on distance with the new AP1 irons?

Chris McGinley: I think the answer to that question quite is simple. We did a lot of research before we developed this line, and part of that research was aimed at what you brought up earlier — positioning these irons properly, because we listened to what golfers said. There’s a lot of golfers out there that want maximum distance and maximum forgiveness, particularly those golfers looking to improve. Distance was an important variable. For a lot of golfers, it was the most important variable and we wanted to deliver on that. That’s really the simple reason behind AP1 being a more distance-focused product. We are in the distance game with this product. But I think it’s important to note that the way we went about it may be a little different. We didn’t want just raw distance; we wanted distance at a playable trajectory so that the player could have the right ball flight to stop the ball near the pin, and we believe our technology package delivers on that. We’re confident that we’re firmly in the distance game, and we’re delivering it in a very effective way.

ZK: You talk about creating distance, but also creating a consistent, playable trajectory. What challenges did you face when you redesigned AP1 to achieve those goals?

Dan Stone: Well, we felt we were really poised already to attack this problem … The materials we’re using allows us to be better suited to make a more playable trajectory from the stronger loft targets that we went after with this generation of product. It’s a lower CG, but with higher inertia values. We also thinned out the face and really created a full cavity. That’s the reason for the acoustical difference.

Previous AP1 irons had reinforced club faces. The new irons have unsupported club faces, which create more discretionary weight and allow the club faces to flex at impact.

The trajectory is really a function of where the CG is. Also, off-center, we maintain ball speed. The AP1 player doesn’t always hit it on the screws. A lot of the distance issues or the trajectory issues come from off-center hits, and that’s where our product really shines, both on center and off-center. We know we have the most playable trajectory in the marketplace in terms of giving players the distance that we wanted them to have, but also making it more consistent.

ZK: If you look back through the years at the lofts of the AP1, you see that the 3 iron had a stock loft of 20 degrees and the PW had a stock loft of 45 degrees. Now the long irons are a degree stronger and the short irons, in some cases, are 2 degrees stronger. Can you explain specifically why you need to do that and what it does for golfers who are a fit for AP1?

Dan Stone: I think originally we were conservative on our lofts. We did not want to give players trajectories that were unplayable. So we kind of started from scratch with this product … We went from about 28 grams to 43 or so grams of tungsten. We didn’t take this project lightly. To reposition the CG location, strengthen the loft, make sure the CG depth was appropriate — especially in the long irons — was essential to achieving the distance parameters we were after. From there, we don’t like to have 5-degree gaps as we go up to the wedges. A lot of our competitors, as you gap from 9 iron to pitching wedge, you’ll see 5-degree gaps. We just don’t believe that a 5-degree gap is something you want to have in your bag when you’re talking about a gap between two irons. We have’t found a way to achieve the appropriate distance gapping between shorts irons. The use of tungsten, lowering CG, having inertia, and the feedback has been very, very good. We knew that going into this. The feedback we were getting in the marketplace was not a surprise. All the testing has proved out that we were able to maintain the trajectory that we had, but achieve more distance and not have balls fall out of the air with the stronger lofts.

ZK: You spoke about tungsten and you see several golf equipment manufacturers use tungsten in their players iron, but no where near as much as Titleist does. In the game improvement category, none of the leading manufacturers have tungsten in their game improvement irons except Titleist. Why is that?

Dan Stone: I think in the game-improvement category, it’s probably price-related. Obviously, these other manufacturers aren’t seeing a significant performance vs. cost ratio that they’re willing to go ahead and pull the trigger on. I’ll also say we have intellectual property in areas of tungsten, in terms of inertia. Not to get into detail with patents, but we have intellectual property in the last five years plus that we feel is pretty strong and has locked some competitors out of the tungsten business in terms of using it in the way we’re using it. We also have manufacturing intellectual properties because of the co-forging process. We know how to put tungsten in irons and we have a lot of experience doing it. It’s not a trivial task. It requires more effort and cost in the manufacturing process to do it, but I would say over the last couples generations we’ve made some significant improvements and strides in making our manufacturing process more efficient as we’ve come out.

Titleist engineers increased the amount of tungsten by 50 percent in the 716 AP1 irons. The 3-7 irons have an average of 42.5 grams of tungsten per head.

We have no plans to go away from the use of tungsten. We believe in it, we know there’s a performance advantage.

I think what you’re seeing in the AP1 is that it’s our best effort thus far, but the acoustic feedback the players get, and the trajectory and feel of the product … a lot of that comes from the use of tungsten. A solid shot feels really good. You can be a little bit more off-center with this club and it still feels solid and sounds good. We went thru a lot of effort to tune the face and I don’t know if you’re aware of the construction, but we got rid of the bar in back of the AP1. We went to a full-cavity concept and that took a little effort. Our initial prototypes, we made a few duds that didn’t sound good. We went with our FEA team and went back and tweaked face-thickness, tweaked the tungsten location until we got it just right. In this situation, each iron is a unique club. Each of them have to be looked at uniquely so that you dial in the appropriate performance. The feel is one of the ones where we can predict that in FEA, but we also have to take the product out and hit it. There were some adjustments after we got our first few sets in that had to go back in and modify to appropriately locate the tungsten and face thickness.

Chris McGinley: I think that’s a key point. As Dan said, it’s our fifth generation iron where we’re using tungsten in a meaningful way. One of the things we’ve learned is that tungsten really helps feel … When you’re making a thinner-faced, distance-oriented iron, it was really key to us to make sure that AP1 had that great feel, and that use of tungsten really delivers there.

Q: Can you explain the co-forging process, and how that’s different from the way tungsten is added to the AP1 irons?

In the co-forging process (which is used on the 716 AP2 and 716 CB irons), the tungsten is put in at the date of the forging itself. So you’re applying tungsten in a cavity and putting steel over that cavity, welding it, and then it goes into a forging operation and it’s forged so that all the material is compressed. In the AP1 program, we use a welding process. The tungsten is mechanically welded because the AP1 is a cast product. So it’s mechanically welded in place, and we’ve become experts in that area because we’ve used the welding process for many years. There are tricks and in-house know-how to be able to appropriately weld that. Because obviously you don’t want to have rattles. You want the tungsten and the steel to work as one. We use a pure tungsten, 17-gram-per-CC tungsten, and we use that high-density tungsten to get the effect, get the inertia. Lower-density tungsten has also been used in the past, but we prefer to use a higher-grade tungsten because it improves our CG properties and inertia values. As a result though, that tungsten does not metallurgically bond directly to steel so we use an interface — a welding — to mechanically lock it in place.

ZK: A lot is said about CG, and as you said the structure of the new AP1 freed up discretionary weight to be moved where it needed to go. Where exactly are you trying to place the discretionary mass to give the golfer the most performance benefit?

Dan Stone: Our CG is placed in the AP1 in the middle of the scorelines. You have a hosel, you have a blade length, and you have the bulls eye. We found players with AP1 hit it, in terms of left-to-right, right-to-left, they hit very good shots when we positioned the CG in the middle of the scorelines. It seems obvious, but probably previous generations of irons were probably a little more heel-biased. We found through testing that we had more consistent trajectories by moving this a little bit more toward the toe. The tungsten is located in the low toe. Part of the reason for that is it counter-balances the hosel and positions the CG low and toward the perimeter of the golf club.

Titleist_716_AP!_thin_face

The new AP1 club faces are made of thin, heat-treated, 17-4 stainless steel, and increase launch angle and ball speed to give golfers more distance.

You asked the question about the ideal location for center of gravity; we’re at 17.5 mm above the ground plane. We think that’s a fantastic location for this AP1 product, and it’s lower than any competitors in this category. The most interesting thing is that it’s got significantly higher inertia values. There’s a few other competitors closer to 18, so we have been able to go a little lower than that and we think that’s a very good spot — 17.5. Those competitors, they’re in the 220-230 range (in terms of inertia) while we’re up in the 275-280 range. That’s a huge difference in terms of what a player’s going to feel, what he’s going to hear and we think our product hands-down give players more confidence just because we’re incorporating a huge amount of tungsten into the golf club. That makes a huge difference, particularly in these long irons categories.

ZK: Each year your engineers are trying to design the best products they can, but another crucial part to performance is fitting. That’s what I want to ask you about, Chris. Golfers who use game-improvement irons have specific challenges. How do the AP1 irons specifically address those challenges.

Chris McGinley: Fitting is certainly a big part of what we do and how we go to market. With game-improvement players, you want to deliver on all those things Dan talked about — playable trajectory, high MOI for speed on off-center hits — and I think the two most important variables with that group are achieving that playable trajectory and finding that right set composition for them. When do they stop their set of irons and move into the long-game category? AP1 long irons are great products, but there typically comes a point with the game-improvement golfer that he no longer has a playable trajectory with those long irons and he needs to move to a different product, typically a hybrid. One of the most important things we did for this launch was we changed our launch cadence. We’re launching hybrids with irons for the very first time and that’s a big deal for us. While 915 hybrids are a great product, we felt this was so important to match irons and hybrids together because the way you can benefit that golfer is to fit them for both irons and hybrids at the same time. You do all the things we do in fitting, you get all the physical specs right — loft, lie, shaft weight, shaft flex — and then you work on their set composition. So where they lose that playable trajectory and those yardage gaps, you go back and improve them with a hybrid club if not two hybrid clubs. I think that’s the biggest thing with fitting with this launch.

ZK: Is there a tip you can offer for golfers interested in a new set of irons? Maybe they’re on the fence between the AP1 and something a little smaller like the T-MB or the AP2. Are there any tips or tricks you can offer for which iron might be best for them?

Chris McGinley: AP1 is certainly a game-improvement iron. At the same time, we have a tour player or two who might put an AP1 long iron in play, and we have a lot of very skilled club professionals who choose AP1, so it really cuts a pretty broad path. At the same time, the AP2, while it has tremendous tour success and heritage, it is a very forgiving iron. We’re talking MOI values that approach the previous generation AP1. Because of that, AP2 really fits from the tour player on up in the 10-, 12-handicap range. If you’re the type of player who prefers a smaller blade size but still wants something forgiving, AP2 is an incredible choice. There’s definitely some overlap there and part of the fitting process that we go through is to determine what model is best for that golfer. Some of that is driven by preference, what they like to look at. A lot of that is driven by their ball flight and what they can do with that. In terms of the T-MB, that’s such an interesting long-game club. We don’t really see that for the AP1 player. We feel T-MB is going to be a great choice for primarily AP2, CB and MB golfers — guys who still need help at the long end of the set. There’s plenty of tour players who fall in that category; they still want help with their long irons, but they don’t want to play a hybrid either because it looks too big to them or it spins too much. That’s where T-MB comes in. We’ve seen a bunch of guys put T-MB in play, and not just a single club, several clubs to help them out at the long-end of the set. Between the four iron models and the T-MB utility iron and the new hybrids, you have a great lineup there to find the right combination for your game.

ZK: Thanks so much for your time, Chris and Dan.

    Picked mine up today after ordering to my specs on Saturday. First range session tonight was fantastic. They feel good, look good, forgive misfits and are long in part do to the lofts. The 4 iron is so easy to hit I am thinking I may no longer need my hybrid. I am a 6 hcp who has gamed player irons including blades mainly because of my ego. Decided to check ego at door and go for something more forgiving and hence 716 AP1. First round Saturday and then off to the desert for vacation and more on course testing

    “Probably in previous generations the CG was a little more heel-biased.”
    I bought the 714 AP-1 irons a year ago and after roughly 5-6 rounds I discovered that my best shots came after I purposely tried to hit the ball closer to the heel. Now I understand why, but it would have been nice if that info was shared by Titleist at the time of purchase, instead of in an article a year later.
    I like my irons currently as they seem almost laser straight, but are a full club short of my Mizuno MP-32, even with their stronger lofts.

    Are they shipping any clubs with AMT’s yet? Are there any AMT’s in any shops yet?

    Recieved mine on the 23rd, and having played a variety of other GI irons these simply take the cake in terms of feel and just overall performance without a doubt

    Will be interesting to see what Vokey wedges they recommend with the 716 AP1s. Kinda will screw up my set if I change from AP2.

From the Forums: Should I play a 3-wood or 5-wood?

Published

on

In our forums, our members have been discussing 3-woods, 5-woods and bag setups. WRXer ‘Cole Fleming’ is currently unsure of his setup, and reached out to fellow members, saying:

“Thoughts on people playing 3 vs 5-wood? I have a high SS 118 with driver 280s + carry. I really never use my 3-wood now as my course doesn’t really have the need unless I move to the back tees. I usually carry it about 260+. I’m ultimately looking for something easier to hit and maybe start trying to use it off the tee some to keep me out of trouble.

I also play a 7-wood. Love it so don’t want them to be to0 close. Ive never even considered or looked at a 5-wood. I have a fitting today so I’m sure I could test them, but wanted somewhat of an idea going into it to tell the fitter so I’m not swinging so many clubs.”

And our members have been sharing their thoughts on the matter, as well as mentioning what has worked best for their game.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • pu_golf88: “I’m dropping the 3 wood this year for a 5 wood. I hit my drivers a similar distance as you and find that my 3 wood isn’t a fairway finder, I really only use it if there’s a dogleg where a driver would go thru where I want to land the ball. I think a 5 wood goes far enough to use it as a fairway finder off the tee when I want more distance than hitting my 3 driving iron.”
  • T626G: “I myself have decided to try a 5-wood. Never really had much luck or need with a 3-wood. Should be easier to hit. I’m going to cut it down a 1/2″ just to help control it and swing easier.”
  • jedc: “Adjustable 5-wood turned down to 4-wood loft (and open looking face is nice). I had a fitting last month and really liked the PXG Black Ops 5-wood.”
