Callaway Great Big Bertha and Big Bertha Alpha 816 Fairway Woods

Callaway’s Great Big Bertha and Big Bertha Alpha 816 fairway woods were designed to make the game easier for an overwhelming majority of the golfing population, yet still deliver tailored performance for special cases. The trick was designing two distinct club heads that covered the needs of most golfers, and then adding enough models and adjustability to account for everyone else.
Typical users of the Great Big Bertha are those who want their shots to fly higher and straighter, while the Big Bertha Alpha 816 targets golfers who want maximum distance or the ability to adjust their launch conditions.
Here’s what else you need to know about the fairway woods.
Big Bertha Alpha 816 ($279)
- Lofts: 14 and 16 degrees (RH, LH), 18 degrees (RH only)
- Shaft: Aldila Rogue I/O 70 (R, S, X), Mitsubishi Rayon D+ 70 (S, X)
- Length: 43 inches
- In stores: September 18
There’s a reason the Big Bertha Alpha 816 fairway wood doesn’t have the words Double Black Diamond in its name. Unlike the Big Bertha Alpha 816 Double Black Diamond driver, you don’t need to be an accomplished golfer to use it.

The Alpha 816 has a matte black crown and no alignment aid, giving it the clean look at address most better players prefer.
[quote_box_center]“The Alpha 816 driver is for the better player, but the fairway wood is not,” said Evan Gibbs, Manager of Product Performance for Callaway. “It can be configured for the best players, but it’s arguably our best performing fairway wood for everyone.”[/quote_box_center]
The Alpha 816 fairway woods can work for two different types of golfers because of their dual center of gravity (CG) positions, which are made possible by two weights that can be installed in either of the two weight ports on the sole of the clubs. One of the weights is heavy (16 grams), while the other is light (3 grams).
Position the heavy weight in the back weight port (the one farthest from the club face), and the club will have a rearward CG that will create maximum forgiveness on off-center hits and a higher peak trajectory. Flip the orientation of the weights, and the club will have a forward CG for a flatter, lower-spinning trajectory that creates the potential for more distance. While forward-CG fairway woods are not as forgiving as rearward-CG designs, they can bring previously unreachable par-4s or par-5s into range, and they also tend to be more workable if you’re a shot shaper.
Last year’s Big Bertha Alpha 815 fairway wood from Callaway also had two CG positions, but Gibbs said there was room for improvement. The 815’s club head was smaller, so there was less space between the weight ports. The weights themselves were also different – one was 30 grams, and the other was 3 grams. Feedback from tour players was that trajectory differences were too extreme: the forward-weight position launched the ball too low, while the rear-weight position launched the ball with too much spin.

The Alpha 816 (left) is 15 cc smaller than the Great Big Bertha fairway wood, which measures 180 cc.
The fix began with a larger club head, which allowed engineers create more separation between the weights. Then they went about optimizing the trajectory of each CG location, which was aided by the addition of a Forged Composite Crown. The lighter structure, which is a first in a Callaway fairway wood, allowed engineers to move several grams of weight lower in the club head to create a higher launch and less spin. That’s a win-win for fairway wood design.
The Big Bertha Alpha 816 fairway woods measure about 165 cubic centimeters, depending on loft. They use Callaway’s Forged Hyper Speed Face Cup, the same technology found in the company’s XR fairway woods — top-rated clubs on our 2015 Gear Trials: Best Fairway Woods list.
Great Big Bertha ($249)
- Lofts: 3 Wood (15.5), 5 Wood (18), 7 Wood (21), Heavenwood (20.5), Divine 9 (24)
- Stock Shaft: Mitsubishi Kuro Kage Black (50-gram range: L, R, S, X)
- Length: 43 inches
- In stores: August 28
The Great Big Bertha fairway woods are designed for golfers whose needs aren’t complicated; they want to hit their fairway woods higher and straighter more often.

A low profile helps the Great Big Bertha launch the ball higher and makes shots from the turf easier.
To that end, the Great Big Bertha is Callaway’s most forgiving fairway wood. It’s large, lightweight, and has a low profile that makes it easy-to-hit from a variety of lies. It’s also designed to fly higher than the Big Bertha Alpha 816, offering the higher launch angle and additional spin that will lead to longer carry distances for golfers with slower swing speeds.
[quote_box_center]“Great Big Bertha is spinnier than XR, and probably our ‘spinniest’ fairway wood,” Gibbs said. “We don’t see these clubs being used by our best players or high swing speed players.”[/quote_box_center]

Great Big Bertha fairways uses Callaway’s Forged Hyper Speed Face Cup for maximum ball speed across the face.
In the spirit of helping non-elite golfers hit better shots, Callaway made the Great Big Bertha in a unique configuration called a “Heavenwood,” which has the loft of a 7 wood but the length and head size of a 4 wood.
The Heavenwood’s 20.5-degree loft offers golfers a higher launch angle, while the larger head and longer shaft create more forgiveness and swing speed. In the past, the model has been a popular one for golfers who have slow swings, as well as those who struggle to get their fairway woods airborne.
The Great Big Bertha 3 wood, 5 wood and Heavenwood use Callaway’s Advanced Opti-Fit adjustable hosel, which gives golfers a 3-degree loft range and two independent lie angles. The 7 Wood and Divine 9 are not adjustable.

Spotted: Luke Donald’s new Odyssey Versa 12 CS putter

Luke Donald has been using a center-shafted Odyssey #7 putter for a very, very long time. Recently Luke decided that he wanted to change it up and try some new putters, according to Joe Toulon, Callaway’s PGA Tour manager.
The new putter is an Odyssey Versa Twelve CS mallet, center-shafted, of course. Odyssey’s Versa high contrast alignment system debuted in 2013 and brought back this year with a full line of head shapes. The Twelve CS is a high MOI mallet with a raised center section and “wings” on the sides. The head is finished in black and then a large white rectangle runs down the center of the putter to aid in aligning the putter towards the target. There is also a short site line on the top, right next to where the shaft attached to the head.
Odyssey’s famous White Hot insert is a two-part urethane formula that offers a soft feel and consistent distance control. The sole features two weights that are interchangeable to dial in the desired head weight and feel. The Versa Twelve CS usually comes with Odyssey’s Stroke Lab counterbalanced graphite shaft but Luke looks to have gone with a traditional steel shaft and a Super Stroke Claw 2.0 Zenergy grip in Red and White.
Our own Andrew Tursky asked Joe Toulon about the type of player who gravitates towards a center-shafted putter:
“Since it’s easy to manipulate the face angle with something center shafted, probably someone with good hands. If you’re a good chipper you may like the face control that a center shafted putter offers.”

7 takeaways from an AWESOME equipment talk with Padraig Harrington

Fans of golf equipment have long known that Padraig Harrington is one of us. Throughout his career, Harrington has been willing to test new products, make changes from week to week, and play with a bag of mixed equipment brands.
What equipment fans may not know, however, is just how brilliant of an equipment mind Harrington truly has.
Ahead of the 2023 Valero Texas Open, I caught up with Harrington to pick his brain about what clubs are currently in his bag, and why. The conversation turned into Harrington discussing topics such as the broader equipment landscape, brand deals in 2023, his driver testing process, why he still uses a TaylorMade ZTP wedge from 2008, square grooves vs. V-grooves, and using a knockoff set of Ping Eye 1 irons as a junior.
Padraig Harrington’s 2023 WITB
Below are my 7 major takeaways from the extensive gear talk with Harrington.
1) Padraig’s stance on equipment contracts, and why he prefers Wilson
Harrington is a longtime Wilson staffer, and although he supports the brand and uses their equipment, he doesn’t use a full bag of Wilson clubs. He finds Wilson’s understanding of a player’s need for flexibility to be beneficial to the player, and it’s attracting more and more professional players to the company (such as Kevin Kisner and Trey Mullinax).
“Wilson wants me to play whatever I’m comfortable with. It’s very important. They’re not a manufacturer that says, ‘We want you to play 14 clubs.’ There’s always a club you don’t like. That’s just the way it is. So Wilson is like, ‘We want you playing well and playing the best clubs for you.’
“I am very comfortable with their irons. I’m very comfortable with their wedges, as you can see. They have an old hybrid 4 iron that I love. They have a new hybrid 4-iron that is too powerful. I put it in the bag last week and I had to take it out. The thing is, I use a 4-iron and a 5-wood. My 4-iron has to go somewhat relative to my 5-iron, and then I have to bridge that gap between 4-iron and 5-wood, so it has to do both. The new 4-iron was going 230 yards. My 4-iron goes about 215-235, maybe 240 on a warm day. And my 5-wood is like a warm-day 265 in the air, but I have no problem hitting it 235, so I can cross it over. But this 4-iron, the new version, it just went. I couldn’t hit the 215 shot with it; it’s just too powerful. That’s why I have the old 4-iron in the bag, but it does the job to bridge the gap…
“As players get more money, they’re less dependent on manufacturers. They need the service of a manufacturer – because, like I need to be on that truck and get things checked. But you’re seeing more players see Wilson as an attractive option because you don’t have to use 14 clubs. If you’re not happy this week with the putter; you know, Wilson has the putters, they have everything, but if you want to chase something else for a moment…remember, there’s two things you’re chasing. If you’re a free agent, it’s not good to be changing a lot. That is a distraction. But it’s nice to have the option that if somebody…like I feel Titleist has come out with a great driver. And I’m able to work my way straight into Titleist and say, ‘Hey, gimmie a go with that. Oh, this is a great driver, I’m going to use this.’ Wilson is aware of that. They want their players to be happy and playing well. Like it’s still 10 clubs, but it’s just not 14 and the ball.
“The irons are great, there’s no doubt about that. They’ve won the most majors. They make a gambit of irons. If you want to use a blade, they have the blade. If you want to use my iron, which is just a good tour composite, it has a bit of a cavity-back, you can do that. If you want to use the D irons that have rockets going off there, you can have them. Like the 4 iron, the one they gave me, it was a rocket! And guys are happy to carry driving irons like that, but mine has to match in with the 5-iron. It was just too high and too fast.
“So yeah, I think you’re going to see manufacturers go more of that way. Our players want to be independent, but the problem is that full independence is not great. You don’t want a situation where you’re turning up – as you see kids who make it into their first tournament, and the manufacturers start giving them stuff, and they’re changing. You don’t want to be the guy changing too much.”
2) The dangers of a 64-degree wedge
Although Harrington himself uses a Wilson Staff High Toe 64-degree wedge, he seldom practices with it. Here’s why he warns against it:
“The big key with a 64 wedge is DO NOT use it. No, seriously, do not use it. It’s a terrible wedge for your technique. That club is in the bag and it gets used on the golf course, and it gets used when it’s needed, but you don’t practice with it, because it’s awful. So much loft will get you leading too much, and you’re going to deloft it. Hit one or two shots with it, then put it away. You’re better off practicing with a pitching wedge and adding loft to be a good chipper instead of practicing with a lob wedge and taking loft off. A 64-degree wedge is accentuating that problem. It’s a dangerous club. It does a great job at times, but it certainly can do harm.
“It’s not bad having it in the bag for a certain shot, but it’s a terrible club to practice with. I literally hit one or two full shots with it, a couple chips with it, and that’s it. I know if I spend too long with it, I’ll start de-lofting.”
3) The interchangeable faces on TaylorMade’s ZTP wedges from 2008 were Padraig’s idea?!
I couldn’t believe it myself, but Harrington says that the idea for TaylorMade to offer interchangeable face technology on its ZTP wedges in 2008 was originally his idea…
“The TaylorMade is obviously attracting a lot of attention, but that was my idea! Myself and a consultant for Wilson, I got him to build changeable faces and he sold that to TaylorMade…that’s fully my idea. He sold that then to TaylorMade, and TaylorMade produced them, which I was happy about. But TaylorMade couldn’t sell them. You can’t get people to clean the grooves, so they weren’t going to buy a new face. Why have 400 faces at home? So I went out and bought these faces to make sure I had them for life. And I was home chipping a while ago, and I have a nice 58. I like the grind on that wedge, and the fact I can just replace the face and have a fresh face every three weeks, it’s just easy, so that’s why that’s in there.”
4) Driver testing isn’t all about speed
“The driver companies know I’m a free agent when it comes to drivers, so every time a new driver comes out, they’ll come to me and say, ‘Hey, would you have a look at this?’
“I will test everything, yeah, but it has to beat what I have in the bag. And Wilson’s new driver is the same. They brought out a new driver and it’s great, but I love the driver I’m using. So I say, ‘Look, guys, not only do you have to be as good as the incumbent, you have to be better, because I already know this and I’m familiar with it.’
“Wilson has built a very, very good driver. There’s know doubt about it. But I love the driver I’m using. And none of these manufacturers can build me a driver that’s better.
“Ball speed gets a driver into the conversation, and then you bring it to the golf course. So the driver has to be going as good as my current driver, and then I bring it to the course and see if I can hit the thing straight. I have gone down the road [of prioritizing speed]…I used a driver in 2014, and it never worked weekends. But it was fast. I used it for about six weeks I’d say – six tournaments – and I missed six straight cuts. It never worked the weekend. It was really fast on the range, but it just wasn’t good on the course.”

5) Playing with knockoff irons as a junior
“I played as a junior for Ireland, under 18’s, and I owned half a set of golf clubs, and they were imitation Ping Eye 1’s. I borrowed the other half set off my brother. We had a half set each. I had the evens, he had the odds. In that tournament, there was a guy playing with Ping Berylliums with graphite shafts. They cost 1,900 pounds. Mine cost 100 pounds, and they were knockoffs. So I played, for my country, with a set of knockoffs. Before I used those knockoff clubs, I used a mixed bag of clubs. As in, I picked up whatever club they had. The 6-iron might go farther than the 5-iron. The 5-iron might go with a fade and the 7-iron might go with a hook, but I knew what my clubs did. Each club had a purpose.”
6) Using square grooves and V-grooves simultaneously
Square grooves – or “box grooves” – were outlawed by the USGA in 2010 because they were said to help golfers spin the ball too much. V grooves are said to provide less of an advantage because they restrict the sharp edges of the grooves, thus reducing the amount of friction imparted on the golf ball. Prior to the rule change, however, Harrington actually used both V grooves and box grooves, and he’d adjust his setup depending on the golf course.
“What’s interesting is, when the box grooves were around – very few people know this – I carried two sets of clubs at all times. I carried a V groove and a box groove.
“Yeah, see, the box grooves were unbelievable out of the rough, spin wise, but if the rough got to a certain level, the ball would come out so low and with spin that it wouldn’t go very far. Your 7-iron coming out of this rough would only go like 140 yards and it wouldn’t get over any trees because it would come out so low. What I was doing was, if I got to a golf course with this sort of a rough, I’d put in a box groove 7-iron and a V-groove 8-iron. If I got in the rough and I had 170 yards, I’d hit an 8 iron and get a flyer, because the 7 iron wouldn’t get there depending on the lie. And I couldn’t get it over things. So if there were trees, you needed the V groove to get over the trees. A box groove wouldn’t get up in the air.
“No one else was doing it. I played with the box groove for a couple years before I realized that in certain rough, you need the V groove to get there. Hale Irwin played a U.S. Open seemingly with no grooves. Off the fairway it’s meant to make no difference. I would disagree, but that’s what the officials would say. But out of the rough you needed the flyers to get to the green. The V grooves were doing that for me. You get your flyer to get of the rough to get the ball there, but then if it was the first cut of rough, or light rough, or Bermuda rough, or chip shots, it would come out so low and spinny that you’d have no problem.
“I can’t believe that people didn’t realize that I was doing this two-groove thing all the time. I swear to you, you could stand here, you would not launch a 7-iron over that fence there if it was box grooves out of light rough, and V groove would launch over it. The launch characteristics were massively different.”
7) Blame the person, not the putter
Interestingly, Harrington, for all his tinkering, has only used a handful of putters. It turns out, there’s a good reason for that — although he’d like his current model to be a few millimeters taller.
“I used a 2-ball when it came out. Then I used a 2-ball blade, which I won my majors with. I always had a hook in my putts, so not long after I won my majors, I went to face-balanced putter because it helps reduce the left-to-right spin. I started putting really badly in 2013 and 2014 – I had some issues. And then come 2016-2017, I just said, look, I putted well with this putter. If I use this putter, I can’t go back and say it’s the putter’s problem. It’s gotta be me. So I went back to the face-balanced 2-ball blade because I’ve had good times with it. I may have only used 5 or 6 putters in my career.
“I’m really happy that I’ve got a putter that I know I’ve putted well with, and I don’t blame the putter. I can’t say that anymore. I don’t blame my tools, I blame myself if I miss a putt. So it comes down to…I know the putter works, then it’s me. Me, me, me.
“You know, I’ve toyed with using other shafts in the putter, and I will look at other putters, but things are askew to me when I look down. So I can’t have a putter with a line on it. It doesn’t look square to the face. I’ve never putted with a putter that has a line on it for that reason. I line up by feel. I know that putter works, I know it suits me, so that’s why I go with that…
“I prefer a deeper putter (a taller face). The one issue I have is I hit the ball too high on the face, but they won’t remodel the whole system to make me a deeper putter. I’ve tried some optical illusions to try and get it where I hit the ball more in the center, but I hit it high. It seems to be going in the hole so I’m not going to worry about it too much. But in an ideal world, if someone came along and said they could make the putter 3-4 millimeters higher, I’d be happy with that.”

TaylorMade survey on ball rollback finds everyday golfers massively against introduction of Model Local Rule

In response to the USGA and R&A’s recent announcement that they plan on rolling back the golf ball for the professional game, TaylorMade Golf issued a survey asking everyday golfers to voice their opinion regarding the topic of golf ball bifurcation. Today, they are sharing the results.
Almost 45,000 golfers across more than 100 countries spanning a variety of ages, abilities and participation levels took the time to complete the survey and have their voice heard, with some of the major findings shown below:
- To the best of your knowledge, do you agree with the proposed golf ball rule?
- 81% No
- 19% Yes
- Do you think average hitting distances in professional golf need to be reduced?
- 77% No
- 23% Yes
- Are you for or against bifurcation in the game of golf (i.e., different rule(s) for professional golfers versus amateurs)?
- 81% Against
- 19% For
- How important is it for you to play with the same equipment professional golfers use?
- 48% Extremely important
- 35% Moderately important
- 17% Not important
- If the proposed golf ball rule were to go into effect, would it have an impact on your interest in professional golf?
- 45% Less interested
- 49% No impact
- 6% More Interested
The results also show that 57 percent of golfers aged 18-34 years old would be less interested in the pro game should the rule come into effect, while five percent said they would be more interested.
“The goal of our survey was to give golfers the opportunity to voice their opinion on this proposed ruling as we absorb the MLR and its potential effects on the everyday golfer. We are grateful that nearly 45,000 golfers across the world felt the need for their voice to be heard. The overwhelming amount of responses show the passion, knowledge and care for the game our audience possesses. Each response and data point is being reviewed as we will utilize this feedback in our preparation to provide a response to the USGA and R&A.” – David Abeles, TaylorMade Golf President & CEO

Yeah, looks like old Cally is trying to dethrone TM as the multiple product release champion! Sheesh,
how many drivers, 3 woods is it now? Oh, and various fairway wood lengths and purposes. Ugh!
This is gettin’ a wee bit out of hand trying to keep up with what I bought, and how that club
has been updated, revamped, repainted, re-weighted, and re-marketed 72 hours later. Maybe if I
drop all my golf mag subscriptions I won’t feel the pressure of having to keep up with the latest
incarnations. Wish I had my old Titleist Pro Model blades, my Cleveland Classic Persimmon driver and
3wood, one Cleveland wedge, and a bellota ball. Da good old days

Such a tired argument. It’s not an investment piece. Go buy what fits you at the beginning of the season and go golf your ball. Quit trying to keep up with manufacturers who are simply trying to improve upon their engineering. I welcome the improvements. Even if they come quarterly. When I’m ready for a new golf club I’ll go take a snapshot of whats available. You certainly don’t have to keep up with releases. (by the way, there is a new BMW 3-series coming out soon. Better go sell yours.)
