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:

    http://www.bridgestonegolf.de/content/node_15813.htm

    and already reviewed on WRX in november:

    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.

What GolfWRXers are saying about the best Nike driver ever

Published

@ukgolfclubsales

In our forums, our members have been discussing Nike drivers. WRXer ‘DixieD’ is currently building up a Nike bag and has reached out to fellow members for driver advice, and WRXers have been sharing what they feel is the best Nike driver ever made.

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.

  • Ger21: “VR Pro LE? I have two I was still playing last year.”
  • mahonie: “The STR8-Fit Tour was one of the best drivers I’ve played. Still have it the garage and take it to the range occasionally…it would possibly still be in the bag if it hadn’t developed a ‘click’ in the head which I cannot fix. Long, straight(ish) and nice sound.”
  • jackr189: “The VR_S is one of the best.”
  • Finaus_Umbrella: “I played the Vapor Fly Pro, and still do on occasion for nostalgia sake. Sound and feel are great, but it demands a good strike.”
  • PowderedToastMan: “I enjoyed the SQ Tour back in the day, the one Tiger used forever. Do I miss it? Not at all, but it was a pretty good club for its time.”

What GolfWRXers are saying about driving irons for mid-handicappers

Published

on

In our forums, our members have been discussing whether mid-handicappers can benefit from a driving iron. WRXer ‘jomatty’ says:

“I average about 230 off the tee on good drives. I can get a little more sometimes, but 230 is probably the average. I’m 42 years old and shoot in the mid to low 80’s. I do not get along with fairway woods very well, especially off the tee, and really don’t get enough extra length over my hybrid to consider using it aside from very rare situations on par 5’s (I’ve considered just going from driver to 19-degree hybrid and getting an extra wedge or something).”…

…and wants to know if he would be better served by a driving iron. Our members have been sharing their thoughts and suggestions.

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.

  • MtlJeff: “If you can shoot mid 80’s, you probably hit it well enough to hit a bunch of different clubs. Personally, I think hybrids are easier to hit….but some driving irons are quite forgiving. I use a G400 crossover that is very easy to hit and looks more iron-like. Something like that you might like. Be careful with some of them though because they aren’t always super forgiving, so you’d have to hit them first.”
  • HackerD: “G410 crossover is my version of a driving iron, feel like I hit it straighter than a hybrid. Just as easy to hit as a hybrid.”
  • hanginnwangin: “I shoot in the low 80s normally and in the 70s on my really good days. I have probably around the same or similar swing speed as you. I have been hitting my 4 iron off the tee on tight holes, and it’s been working pretty well so far. I hit it about 190-220. I have a 4 hybrid but just can’t hit it as consistently as the 4 iron, and it doesn’t even go much farther. I have a 5 wood which I only use for 220+ yard par 3s or wide-open fairways. Basically, it’s all personal preference and what you do best with. Everyone is going to be different. Try new stuff out and see what works. But if irons are the strongest part of your game (they are for me as well), I would give the 4 iron a shot. You can get a lot of roll out on the tee shots with it,”
  • Hellstrom: “Don’t laugh, but I bought a 17* hybrid with a senior flex shaft at a garage sale for $5, and I can hit it nice and easy and keep it in play without losing any distance. My driver SS is between 105 and 110 usually and swinging this thing feels like swinging a spaghetti noodle, but it works. I don’t have it in the bag all the time, but I do use it for certain courses. I take my 6 iron out and throw that in, so if I struggle with getting the ball off the tee, I just go to that.”
