Spotted: Callaway Mack Daddy 4 prototype wedges, X Forged driving iron
Tinker season has returned!
With the 2016-2017 PGA Tour season ending at the Tour Championship on Sunday, it’s technically the offseason despite some of the best players in the world competing in the 2017 Presidents Cup at Liberty National Golf Club. Although it’s an important and patriotic competition, it still marks the start of new equipment releases, and PGA Tour players trying out new equipment.
On the range at Liberty National, we spotted new Callaway Mack Daddy 4 wedges — the company says they are in the prototype phase — and a new Callaway X Forged prototype driving iron in the bag of Phil Mickelson.
Callaway Mack Daddy 4 prototype wedges
The Mack Daddy 4 wedges look similar to the company’s previous MD3 Milled wedges, which also had four weight ports in the rear cavities that were said to reposition center of gravity (CG) higher in the wedges for a lower launch and higher spin. The overall look of the wedges, however, bear more of a resemblance to its Mack Daddy 2 wedges. The photos also show that “milled” is stamped on the hosel of the Mack Daddy 4 wedges.
Maybe the Mack Daddy 4 is a best-of-both-worlds design that draws from the constructions of both the Mack Daddy 2 and 3 wedges. We’ll have to wait and see, for now.
“This is a Callaway prototype wedge that we are currently testing with our professional staffers,” a Callaway representative told us. “It is a prototype as of now.”
Callaway X Forged Driving Iron
In Phil Mickelson’s bag, a well-known club tinkerer, we spotted a Callaway Epic Pro iron, X Forged 2017 irons, Callaway Apex MB irons, and a never-before-seen X Forged 18-degree driving iron. Unlike Callaway’s previous Apex UT driving iron that had a weight port in its sole, the X Forged driving iron we spotted in Phil’s bag has a clean sole. It does, however, sport an expectedly wider sole than the new X Forged 2017 irons that were recently unveiled in Japan.
“These are Callaway prototype irons that we are testing with our professional staffers,” a Callaway representative told us. “They are prototypes as of now.”

TaylorMade Golf’s MySpider program underwent a substantial overhaul over the last month. Firstly, the company launched the option to customize the Spider ZT model, and now the program has returned with the MySpider Tour and MySpider Tour X.
The revamped page now gives golfers complete control over every visual and functional detail of their putter on the popular Tour and Tour X head, with every cosmetic idea thought of. In MySpider Tour, golfers can choose from four head finishes, 16 paint fill colors, nine Surlyn face insert colors, three aluminum insert options, six sightline configurations, and four hosel options — L-neck, small slant, double bend, center shaft. Six sightline options are available in MySpider Tour, including the optically engineered True Path alignment system. MySpider Tour X gives builders the option of four head finishes, four hosel configurations, and five sightline options, also including True Path alignment.
One of the more interesting features of the new MySpider program is the availability of three distinct face insert options. Along with the usual Surlyn Pure Roll insert trusted by Scottie Scheffler and Rory McIlroy, which can be customized from nine colors, golfers can now also select firmer options. Two are offered with the black aluminum Pure Roll insert, slightly firmer than the traditional insert, or for the firmest feel, golfers can choose from two colors of milled aluminum inserts.
Another fun addition to the MySpider Tour is the ability to use the “Tommy Sightline.” The custom alignment aid design, which was first drawn onto Tommy Fleetwood’s putter by PGA Tour Rep James Holley, is based on the milled sightline on his Spider ZT head. There are five shorter lines on the left and right of a longer central line serving as the traditional short line alignment aid.

Then and now: Comparing Rory McIlroy’s current setup to his record-breaking 2019 Canadian Open victory
In Rory McIlroy’s first appearance at the 2019 RBC Canadian Open, he crushed the record books to earn his 16th PGA Tour title in dominating fashion, winning by seven shots over Shane Lowry and Webb Simpson.
McIlroy’s score of 22-under-par 258 is the lowest 72-hole score to date at the Canadian Open, and his closing 61 is also the best final-round score in the history of one of golf’s oldest tournaments. Finally, with his win in 2019, McIlroy became only the sixth player to win the career Triple Crown, adding to his victories at the U.S. Open in 2011 and The Open Championship in 2014, joining Tommy Armour, Walter Hagen, Arnold Palmer, Lee Trevino and Tiger Woods in a coveted list.
So, with that, why not compare his current setup to the clubs he used to break all the records?
Driver
2019: TaylorMade M5 (9 degrees), Shaft: Mitsubishi Tensei CK Pro White 70 TX
2026: TaylorMade Qi4D (9 degrees @8), Shaft: Fujikura Ventus Black 7X (45 5/8 inches)
McIroy led the Tour in Strokes Gained: Off-the-Tee in 2019; he’s doing the same in 2026. Between now and then, McIlroy has switched from the Mitsubishi Tensei CK Pro White 70 TX (a shaft with slightly more feeling in the tip) to the original Fujikura Ventus Black 7X, having just made the change to the heavier version from playing the 60X.
What’s interesting about McIlroy’s 2019 setup is that the weighting on his driver is actually set in the high-draw setting, using the T-Track weighting system, whereas in the Qi4D, he’s currently using a heavily rear-weighted setup. (Two 13-gram weights in the rear and only two 4-gram front weights.)
The TaylorMade M5 driver he played in during his Canadian Open win was the company’s first head that they claimed to design to initially exceed the USGA’s COR limit, and then injected with tuning resin to bring it back in bounds.
Fairway woods
2019: TaylorMade M6 3-wood (15 degrees), Shaft: Mitsubishi Tensei CK Pro White 80 TX; TaylorMade M5 5-wood (19 degrees), Shaft: Mitsubishi Tensei CK Pro White 90 TX
2026: TaylorMade Qi4D 3-wood (15 degrees), Shaft: Fujikura Ventus Black 8X; TaylorMade Qi4D 5-wood (18 degrees), Shaft: Fujikura Ventus Black 9X
The TaylorMade M6 fairway wood that McIlroy was using during the 2019 season is still in the bag of some of the best golfers on Tour in 2026. Just check out Justin Rose’s winning setup from the Farmers Insurance Open earlier this year. This year, though, McIlroy has still been searching for his top-end-of-the-bag setup, having played both the new Qi4D and the Qi10, which he won the Masters with.
The same shaft swap can be seen in the fairway woods as the driver, along with slightly less loft on the 5-wood.
Irons
2019: TaylorMade P750 (4) Buy here, TaylorMade P730 (5-9), Shafts: Project X 7.0
2026: TaylorMade P760 (4), TaylorMade Rors Proto (5-9), Shafts: Project X 7.0
The biggest difference between McIlroy’s custom set and the stock P730s is the groove design. While the P730s were constructed with 14 MX-9 grooves on their milled faces, McIlroy’s proto heads instead use the higher-spinning, 16-groove layout of the TW2 grooves. Other big differences between the sets are that McIlroy’s 7- and 8-irons have thinner toplines, are 1 degree stronger in loft, and are 1/4 inch longer than the original P730 builds.
With McIlroy’s 4-iron, the switch from P750 to P760 sees a transition to a two-piece construction with Speed Foam in it, which allows McIlroy to launch the ball slightly higher, with more workability.
Wedges
2019: TaylorMade Milled Grind (48-09SB), TaylorMade MG Hi-Toe (52-09SB, 56-09SB, 60-LB09), Shafts: Project X Rifle 6.5
2026: TaylorMade MG5 (46-09SB, 50-09SB, 54-11SB, 60-08LB @61), Shafts: Project X 6.5 (46-54), Project X 6.5 Wedge (60)
Between 2019 and 2026, McIlroy’s focus on his short game has been much more apparent. It was the reason why he switched back to the TP5 golf ball, to help with launch, spin and control with his wedges leading up to his career Grand Slam victory in 2025. The most apparent changes to McIlroy’s wedge setup are his lofts and bounce. He’s slowly delofted his pitching to a sand wedge, but has increased the loft on the lob wedge, bending his current 60-degree to 61. With that, adding more loft to his lob wedge also slightly increases the bounce and leading-edge sit point, so, as a result, he plays a lower-bounce lob wedge compared to 2019. The MG5 wedges are also softer than the first Milled Grind option from 2019. McIlroy also no longer plays the full-face grooves found on the Hi-Toe.
Putter
2019: TaylorMade Spider X
2026: TaylorMade Spider Tour X
Notice anything similar. Yes, the copper finish on Rory McIlroy’s Spider X putter in 2019 is a slightly more reflective finish than the recently released torched PVD finish. McIlroy was using the True Path alignment system, but now uses only a single white sightline.
Ball
2019: 2019 TaylorMade TP5 (#22)
2026: 2025 TaylorMade TP5 (RORS)
As mentioned above, McIlroy had transitioned from the TP5 to TP5x golf ball since his victory in Canada in 2019, but now is black with the same style of golf ball as his victory at Hamilton Golf & Country Club.
Grips
2019: Golf Pride Tour Velvet Cord
2026: Golf Pride MCC
Interesting, McIlroy actually used Golf Pride’s Tour Velvet Cord grips during his victory in 2019 (it was during a 2+ year switch to the corded TV) as opposed to his usual MCC grips, which he has played for most of his career.

It wouldn’t be Fall if Callaway weren’t debuting their new and improved wedges from a few months back. My oh my, how do Titleist, Ping, Mizuno, Cleveland and dare I say Taylormade compete in the wedge segment? They only release new wedges every 18-24 months.
Overengineering? To a T.
FWIW, I do like that they’re not even bothering with rebadging.

Read this “article” three times and have not figured out what makes these BETTER than Mack Daddy 2 wedges? It says it ” reposition center of gravity (CG) higher in the wedges for a lower launch and higher spin” How much lower and how much spin?

From Wikipedia:
“Overengineering (or over-engineering) is the designing of a product to be more robust or complicated than is necessary for its application, either (charitably) to ensure sufficient factor of safety, sufficient functionality, or because of design errors. Overengineering can be desirable when safety or performance on a particular criterion is critical, or when extremely broad functionality is required, but it is generally criticized from the point of view of value engineering as wasteful. As a design philosophy, such overcomplexity is the opposite of the less is more school of thought (and hence a violation of the KISS principle and parsimony).
Overengineering generally occurs in high-end products or specialized market criteria, and takes various forms. In one form, products are overbuilt, and have performance far in excess of needs (a family sedan that can drive at 300 km/h, or a home video cassette recorder with a projected lifespan of 100 years), and hence are more expensive, bulkier, and heavier than necessary. Alternatively, they may be overcomplicated – the design may be far more complicated than is necessary for its use, such as a modern text editor asking whether files should be saved in ASCII, EBCDIC or various multi-byte formats. Overcomplexity reduces usability of the product by the end user, and can decrease productivity of the design team due to the need to build and maintain all the features.
A related issue is market segmentation – making different products for different market segments. In this context, a particular product may be more or less suited for a particular market segment, and may be over- or under- engineered relative to an application.

The golf club industry and over-engineering…. so true.

IDIOT
An idiot, dolt, dullard or (archaically) mome is a person perceived to be lacking intelligence, or someone who acts in a self-defeating or significantly counterproductive way. Along with the similar terms moron, imbecile, and cretin, the word archaically referred to the intellectually disabled, but have all since gained specialized meanings in modern times. An idiot is said to be idiotic, and to suffer from idiocy.

You are the definition. So true//
