Grooves on Grooves: Callaway launches new Mack Daddy 4 wedges

Published

on

“Let’s do something else,” said Callaway’s Chief Designer and wedge-making legend, Roger Cleveland when talking about designing the new Callaway Mack Daddy 4 wedges.

And something else, he did.

Callaway’s Mack Daddy 4 wedges, which the company officially launched on Tuesday, use a new “groove-in-groove” technology that features raised micro-ridges between the main grooves on the faces. Rather than these ridges going below the surface, however, they’re actually “surface positive,” as Callaway explains it; that means they protrude above the surface. Therefore, the grooves and micro-ridges create more points of contact for the golf ball, and they create additional friction to induce more backspin.

In fact, Cleveland himself was so excited about the design, he stood up during our interview and drew out the design on a whiteboard. Professor Cleveland, if you will.

Using new, proprietary cutters, it takes 12 minutes per head to cut the grooves, according to Cleveland. Using a progressive design throughout the set, the lower-lofted wedges — 52 degrees and below — use “20D” grooves, while higher-lofted wedges — 54 degrees and above — use 5D grooves. That means, overall, the higher-lofted wedges are designed to create more spin for greater control around the greens, and the lower-lofted wedges will behave more like your shortest iron. Each of the wedges also have an added groove — Callaway calls it a “nip it” groove — near the leading edge that’s designed to induce more spin when you catch the ball a bit thin.

Maybe the new groove design is why so many PGA Tour players are switching into the wedges so quickly. Sergio Garcia already won with them in the bag at the Andalucía Masters, and Brendan Grace won using them at the Nedbank Golf Challenge. In the 2017 RSM Classic, in fact, there were 30 Mack Daddy 4 wedges already in play.

Grooves aren’t the only difference you’ll notice in the new Mack Daddy 4 wedges, however. Based on Tour feedback, Callaway has designed the wedges with a more compact shape, straighter leading edges, tighter leading edge radii, and slightly more offset throughout the line, according to Callaway.

The MD4 wedges have a progressive offset in the set in order to better blend looks-wise into your set of irons.

“Tour pros like only a subtle amount of leading-edge radius,” said Cleveland, according to a press release. “In the Mack Daddy 4 we gave them enough to make a performance difference while still pleasing the eye.”

As part of the Mack Daddy 4 wedge line, there are now 4 grinds: C-grind, S-grind, W-grind and a new X-grind that has a narrow sole but with high-bounce. Here is the rundown of what each of the grinds delivers, according to Callaway:

  • C-Grind: “Increased relief, especially at the heel, making it easier to play shots with the face open. Ideal for medium-to-shallow attack angles and/or firm course conditions. 8-degrees of bounce.”
  • S-Grind: “Medium-width sole with slight chamfer at the back and moderate heel relief to keep the leading edge low through impact, promoting solid contact on open-faced shots. 10-degrees of bounce.”
  • W-Grind: “Sole is wider at the center and toe and narrower at the heel, with moderate heel relief and generous front-to-back camber. That prevents digging without increasing bounce, and keeps the leading edge close to the turf at impact. Great for open-faced shots. More versatile than our previous W Grind. 12-degrees of bounce.”
  • X-Grind: “The newest grind features a narrow, high-bounce crescent sole, with the low point near the front. Excellent for moderate-to-steep attack angles and medium-to-soft course conditions. 12-degrees of bounce.”

The Mack Daddy 4 wedges, which are made from 8620 carbon steel, come in both Platinum Chrome and Matte Black finishes. Like the previous Mack Daddy 3 wedges, the Mack Daddy 4 wedges have four weight ports, and they have milled-aluminum medallions that progressively raise CG (center of gravity) as loft increases to help dial in ball flight, spin and feel appropriately for each loft.

Available lofts include 46, 48, 50, 52, 54, 56, 58, 60 and 64-degree options, totaling 21 loft-bounce combinations. The wedges will come stock with True Temper’s Dynamic Gold Tour Issue 115 shafts and Lamkin UTx grips. Mack Daddy 4 wedges will be in stores on January 26 and will sell for $149 apiece.

    I like the look, but will stay with my PM Grind wedges. I don’t understand why more wedges do not have grooves across the entire face, like the PM Grind. Even if I miss off the toe, the shot is still acceptable.

    Funny, the Bridgestone Tour B wedges have also that “new “groove-in-groove” technology”,
    already mentioned in a press release in august last year:

    and already reviewed on WRX in november:

      Cleveland/Srixon have been using this for a while now.

    These hi-tech wedges are only effective for tour players with higher speed swings. Only the top 1% of golfers, which includes gearhead wannabes, will entertain buying these contraptions.
    Btw, in the 1967 book Search for a Perfect Swing (SPS) they tested a smooth grooveless wedge and found insignificant differences in performance compared to a grooved wedge. The testing was done under scientific condition of that time so perhaps the results would be different with these Cally wedges with the fancy face milling.

      I think wedges are one of the few areas of most amateur golfers games that can be in any way like a Tour player. Not the full swing shots, but those around the green are well within the reach of a normal golfer. If you look at a 30 yard pitch, the speed a Tour player uses and an amateur will be very close (providing they are playing the same kind of shot) as the goal isn’t about maximum yardage but the correct yardage. Of all the gear in your bag, wedges and your putter are the clubs that allow you to play a “tour players” game as they don’t rely on physical strength and speed to work

      Grooves are useful once there is anything in the way of the contact between ball and club, so a grooveless wedge is fine from a perfect clean lie, but poor everywhere else, hence all wedges have grooves.

      Stan – Where or how are you coming up with this nonsense?

      The groves are for poor lies. A grove wedge in the rain removes about 2 tsp of water from between the club face and ball. The groves also improve spin out of the rough.

        So, if you hit different types of wedges off a clean tight lie there would be no significant difference between their performance results?

          I buy that….isn’t there an old article that proves that??

      Flawed study.

      Grooveless wedges only perform good under perfectly clean conditions. Like off a turf mat and a perfectly dry/clean ball. If any moisture gets on the ball or clubface the whole thing goes haywire.

      Wedges are designed for slower swing speeds, unlike drivers. Along with putters they are the most relevant.

Forum Thread of the Day: “New Ping G410 Driver?”

Published

on

Today’s Forum Thread of the Day comes from hervygolf21, and it surrounds the new G410 driver from Ping that is allegedly set for release at the beginning of 2019. Our members have found out plenty of information on the latest driver from Ping since the thread began, apparently, and here’s a quick look at some of the features you might expect from the new model (if you take forum members’ word for it).

According to the thread, the PING G410 will be black with red accents, will have a higher MOI than the current G400 model, will still contain the Ping Turbulators and will be offered in 12 degrees without draw weighting. It’s also believed that the G400 Max will remain current until July/August 2019, but at a lower price point.

Here are a few posts in the thread reflecting on the news, but make sure to check out the entire thread and join the discussion at the link below.

  • lc1342: “Love both the G400 LST and G400 Max, but if they are bringing out something better… I’ll take it!”
  • cz13x4: “This sounds like a very interesting update. Not keen on red but very interested to see what comes out.”
  • roho: “Late January?  Sounds like maybe a PGA Show unveil in Orlando.”

Ben Hogan adds Ft. Worth “White” to iron lineup

Published

on

After the launch of Diamond Black Metal finish Ft. Worth “Black” irons earlier this year, Ben Hogan’s nickel-chrome Ft. Worth irons are back…sort of. The Texas-baed company today announced the launch of Ben Hogan Ft. Worth White irons.

Now with respect to the “White” designation, If you’re skeptical/confused, well, let’s just have a look at a comment on BH’s Instagram post announcing the iron launch and the company’s response…

jonmodica: “Very unclear the changes from previous model… also… white? It’s chrome…..”

Benhogangolf: ”@jonmodica More progressive specific to each club head, a more aggressive V-Sole pattern and the ‘white’ is opposite of the popular and newly designed Ft. Worth Black.”

There you have it, folks. “White” as in contrast to the Ft. Worth Black irons, and the Ft. Worth White is not merely a re-issue of original chrome Ft. Worth, according to the company.

With respect to the changes to the V-Sole system, the company said this in its marketing materials for the Ft. Worth Black.

“Feedback from strong players and robot testing indicated that the leading edge could be increased on certain irons, and trailing edge softened … especially with less-than-full shots in the shorter irons.”

“So, in our ongoing quest to design and manufacture the best clubs in golf, we’ve modified the V-Sole Technology used on the Ben Hogan Ft. Worth BLACK slightly. The sole maintains the same basic design principles as the original V-Sole but has been optimized for each iron in the set. In effect, we’ve strengthened the leading edge from the sole to the face on some of the Ft. Worth BLACK irons, while reducing the trailing edge bounce on others.”

Obviously, the company scrapped the PreciseLoft system introduced with the original Ft. Worth irons. That system offered four loft profiles, all with consistent four-degree gaps. After finding the vast majority of players preferred the “mid-high” launch profile, the company did away with the others…and returned to tradition iron number (rather than loft) stamping on the toe.

The aforementioned lofts in the 4-PW set range from 22 degrees to 46 degrees.

“The Ft. Worth White Irons are illustrative of how Ben Hogan Golf Equipment Company interacts with and listens to its customers,” said Scott White, President and CEO, Ben Hogan Golf Equipment Company. “On the heels of our sales success with the Ft. Worth Black Irons, we found many ‘traditionalists’ who wanted to play this iron design with the standard nickel-chrome finish, so we accommodated them with this launch.”

Ft. Worth White irons are available for purchase on the Ben Hogan website exclusively for $700.00 per seven-piece set (4-PW).
