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.

    • Huh?

      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.

A Deep Dive: The equipment timeline of David Duval, 1993-2001

Published

on

Like Tiger, David Toms, and Fred Couples there are certain players that I have been obsessed with for years. If you go to my Instagram, you can see it in plain sight. When it comes to DD it was more than the what, it was the why, the how that sparked my curiosity. Let’s face it, in 2000 with the Mossimo gear, Oakley shades, jacked-up physique, and on Titleist staff, was there ever a cooler looking player?

No. There wasn’t or isn’t.

That’s where my interest in Larry Bobka came about. I saw David and Larry walking the fairways of Sahalee at the ’98 PGA Championship.

At the time, I was already knee-deep in David Duval fandom but that experience took me over the top. Bobka had a handful of clubs in his hands and would pass DD a 970 3-wood, Duval would give it a rip and the two would discuss while walking down the fairway. Of all my time watching live golf, I have never been so awestruck.

This is an homage to David’s equipment during his prime/healthy years on the PGA Tour. From his early days with Mizuno, into the Titleist days, and finally Nike.

1993-1995 Mizuno

*This was an interesting time for Duval from an equipment standpoint. The pattern of mixing sets to put together his bag began and it was the time he transitioned from persimmon (Wood Bros driver) into metal woods. It was also the beginning of his long relationship with Scotty Cameron, a relationship that still stands today.

What was in the bag

Driver: TaylorMade Tour Burner 8.5 w/ Dynamic Gold X100 (*he also played with the Bubble XHKP Prototype)

3-wood

King Cobra @14 w/ Dynamic Gold X100

TaylorMade Tour Issue Spoon @13  w/ Dynamic Gold X100

1995: (2,3) Mizuno TC-29, (4-PW) Mizuno TN-87 with Dynamic Gold X100

Wedges: Mizuno Pro (53, 58) with Dynamic Gold X100

Putter: Scotty Cameron Classic Newport (35 inches, 71 lie, 4 degrees of loft)

Ball: Titleist Tour Balata 100

Glove: Mizuno Pro

1996-2000 Titleist

The beginning of the Titleist years started off quietly. There wasn’t any new product launched and David wasn’t quite the star he would become 12-18 months later. However, it gave Titleist the opportunity to get to know DD and his overall preferences, which aren’t dramatic but certainly unique. He didn’t win in 1996 but did qualify for the Presidents Cup Team and finished that event off at 4-0. So the buzz was going in the right direction and his peers certainly took notice.

It was 1997 that things took off on all fronts and it was the year that Titleist made David Duval the face of the DCI brand and with that decision spawned the greatest cast players cavity ever: the 962B—and also equipped David Duval to go on a 3-year run that was surpassed by only Tiger Woods.

Hence the deep dive article I wrote up earlier this month

2001: Nike Golf and The Open Championship

The relationship with Titleist Golf ended quickly and when David showed up to Kapalua with a non-Titleist stand bag the rumor mill went nuts. The story (although super speculative) was that David opted out in the middle of a $4.5 million per year deal with Acushnet, a lawsuit followed, but Davids’s stance was that he had a marquee player clause that allowed him to walk if he wasn’t “marquee” aka highest-paid.

Apparently he had a point, Acushnet had recently inked big deals with Davis Love and Phil Mickelson leading someone on the outside to do the math. However, I’m not an attorney, wasn’t there, and have no clue what the legality of any of it was. Point is, he walked and landed at Nike with a new head-to-toe contract.

SPEC TALK

Over the years the one constant was David’s iron and wedge specs. As a shut-faced player he has always favored traditional lofts in his irons. However, a cool thing to note is his lie angles remained constant 59.5 (2-4), 60 (5-9). The running theory here was being a shallow (low hands) and shut faced player, keeping the lie angles at a constant (flatter) lie angle allowed him to feel like his angle of attack could remain the same for each iron. It’s just a feeling but that’s what he did. If the “why of it” is true, it looks like he was doing Bryson things before Bryson did.

David Duval Iron/Wedge Specs

Loft/Lie/Length/SW

  • 2-17/59.5/40.25/D5
  • 3-20.5/59.5/39 1/6/D4
  • 4-24/59.5/38 9/16/D4
  • 5-27/60/38 1/16/D4
  • 6-30.5/60/ 37 9/16/D4
  • 7-35/60/37 1/16/D4
  • 8-39/60/36 9/16/D4
  • 9-43/60/36 5/16/D4
  • P-47/61/36/ 1/16/D5
  • GW-53/62/35 5/8/D4
  • LW-58/62/35 9/16/D6

Whew…since this prolific run, David transitioned into some interesting projects with smaller companies like Scratch, B.I.G Golf (AKA Bio-engineered in Germany), back to the mainstream with Nike, and most currently Cobra Golf.

I hope you all enjoyed this walk down memory lane with me, Duval is not only fascinating from a career standpoint but digging into the equipment of DD has been quite the experience.

“Why can’t I hit my new irons to a consistent distance?” – GolfWRXers have their say

Published

on

In our forums, our members have been discussing irons and how to hit your numbers consistently. WRXer ‘Hubb1e’, who is a 15 handicap, is having issues and says:

“I recently upgraded from 20 year old Taylor Made 360 irons to a set of custom-built Callaway Apex 19 Forged irons. Old irons were traditional cavity back. New irons are categorized as players distance irons. Both have the same fit.

My new 3 iron will go 230 yards or 130 yards and not even make it far enough to reach the fairway. My new 7 iron will typically go 160 yards but will often will fly 175 yards or drop out of the air at 120 yards. I can’t control the distances of my new irons, and I spent a fortune custom fitting them to my swing. Why is this happening? This was never an issue with my old irons. A bad hit would go 10-20% shorter, but I never had balls fly over the green or completely fall out of the air. What is going on with my new equipment?”

Our members offer up their solutions in our forum.

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.

  • ThreeBoxers: “Strike quality is your answer. Tech or no tech, irons will not have 50-yard distance discrepancies. Not super familiar with the Apex irons, but they’re pretty forgiving no? You might lose 10 yards on toe or heel strikes but 40, 50? You’re probably hitting it heavy. If they have a beveled edge, it may mask the feeling of hitting it fat a bit, but not the result. My Mizunos have a pretty aggressive front edge grind which helps a ton on heavy shots. It’s the difference between landing 15 yards short and 50 yards short. +1 on using foot spray to check impact.”
  • extrastiff: “It also would not hurt to check your swing speed. Even strike being terrible that’s a large discrepancy. Maybe your last build had a weight that helped you get consistent swing speed.”
  • WristySwing: “I would say inconsistent strike is the biggest issue. Now that can mean a couple of things. It could mean you, as in the person swinging, are not hitting the ball properly because of inconsistent delivery. The other option is the fit is bad, and it is causing you to be extremely inconsistent because you cannot feel the head. It might be a little bit of column A and column B. However, I would lean more towards column A in this scenario because even a horrifically misfit set someone could get used to it eventually and not have 100 yards of discrepancy in carry shot to shot. I’ve seen people who are playing 50g ladies flex irons with fat wide soles who are very shallow and swing a 6i 92mph still not have 100 yards of carry flux with their sets. If your miss is toe-side 9/10x that is because you are coming too far from the inside. When you get too stuck on the inside you typically stall and throw your arms at it. When you break your wrists (flip)/throw your arms at it you get a very inconsistent low point average that often manifests in extremely fat or thin strikes….typically fat since your squat and rotate is out of sync with your release. As others have said, get some impact tape/foot powder spray and see where you are actually making contact. Then if you can get on a video lesson and see what the issue is. As of right now, we can all only assume what is going on. If your low point control is good, you don’t get stuck, and you are hitting it in the middle of the head — then fit comes into question.”
  • larryd3: “I”d be on the phone to my fitter and setting up a time to go back in and see what’s going on with the irons. You shouldn’t be getting those types of results with a properly fit set of irons. When I got my fitting earlier this year at TrueSpec, the fitter, after watching me hit a bunch with my current irons, focused on increasing the spin on my irons, not on distance but on consistency. So far, they seem to be working well when I put a decent swing on them.”
  • fastnhappy: “One possibility that wouldn’t necessarily show up indoors is sole design and turf interaction. You may have a real problem with the newer clubs because of a sole design that doesn’t work for your swing. That’s hard to tell when hitting inside off a mat. If so, you’d see major distance inconsistency because of strike. The feedback I’ve seen on the players distance irons is exactly what you’re describing… difficult to control distance.”

In our forums, our members have been discussing their favorite watches for golf. WRXer ‘Sourpuss’ asks fellow members: “Dealer’s choice, cost is of no concern. What would you wear if you could afford it? Top 5 of your choice?” and WRXers have been weighing in with their choices in our forum.

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.

  • sheppy335: “Garmin S40. Love the feel and look.”
  • golfkrzy10: “Apple iWatch with the hole 19 app. Yardage, score, fway, and putts. Perfect for my minimalist walking views on the golf course.”
  • jcboiler: “Second the Apple Watch. Need to look into the apps though.”
  • Deadsquiggles: “If it didn’t bother me to play with a heavy watch, I’d wear my Deep Blue NATO Diver Automatic. But instead, I wear my cheap GShock.”
  • Golfjack: “I thought I was going to come in with a witty comment about my expensive watch, but looks like I’m late! Anyway, I wear my Galaxy Active 2 normally now. Used the Golf Caddie app for a few times. It worked well enough, but I don’t see it helping too much. Still prefer using apps on the phone if I need GPS info. Otherwise, I just use my rangefinder.”
