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:

    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.

WRX Spotlight Review: T Squared TS-713i Standard Series putter

Published

on

Product:  T Squared TS-713i Standard Series Putter

About T Squared: T Squared Putters is a small putter manufacturer just south of Buffalo, New York. The company was founded by Tony Tuber who created his first prototype putters, after hours, in his father’s machine shop. Since then Tony and his father have been creating high-quality putters in the same facility that creates high precision instruments for the medical field. They pride themselves on creating the highest quality, most precise putter they can offer. They offer a few different head shapes from small traditional blades to high MOI mallets and even a custom program to get exactly what you want.

The Ts-713i Standard Series is based on the Ts-713, the first prototype that Tony created. It is a blade-style putter with a slightly longer flange and a unique face insert milled from 6061 aluminum. The body of the Ts713i is milled from a solid block of 303 stainless steel that is produced in the USA and has a Teflon backing between the body and face insert.

This Teflon backing helps give the putter a softer feel at impact and reduce any unwanted vibration. Details are what T Squared is all about and the neck of the putter shows off their milling expertise. The neck is similar to a plumbers neck, built with multiple pieces and offering some cool texture on the section bonded to the head. Another great detail is that all the silver markings on the putter are not filled with paint, they are milled into the head. T Squared finished the head in a sharp matte black and then milled all the markings on the putter for a unique, shiny silver look that really stands out. Ts-713i putters are built for customizing and have a ton of options that you can select if you would like to build something totally unique

On the green, the T Squared TS-713i really performs fantastic. I found the feel at impact very solid without any unwanted vibration. The impact produces a muted click and soft feel that I wasn’t expecting from this aluminum insert and thin face. The deep milling and Teflon coated back to the insert really work together to produce a great, responsive feel that I enjoyed. Deep milling usually makes me a little worried because it can soften the putter too much and lose that feel we all demand.

The TS-713i has no issues and transmits impact feel back to your hands with ease. Mishits are a little louder and harsh, but nothing even close to unpleasant. I have used putters that don’t feel as good on perfectly struck shots as the TS-713i feels on mishit putts. Distance and accuracy on those mishit putts are not as drastic as you would expect with a blade putter. I often just missed the cup by small margins when I struck a putt on the toe or heel of the TS-713i. There aren’t too many blade putters that have shown this level of forgiveness on the green for me.

The “T” alignment aid on the flange of the putter is large and easy to use. Not only do you get a straight line from the face to the back edge for alignment, but the back of the “T” also helps you square the putter up to your target. The Pure grip is not my thing, and it would be great for T Squared to offer a few more options, but that is an easy fix and a very minor criticism.

Overall, the T Squared TS-713i is a great putter from young Tony Tuber that exceeded my expectations. His attention to detail, precision milling, and take on a classic head shape offer golfers something different without sacrificing any performance. If you are looking for a great feeling putter that is made in the USA, you should take a look at T Squared and see what they can make for you.

Forum Thread of the Day: “Wilson Staff Irons – First Impressions”

Published

on

Today’s Forum Thread of the Day comes from balls_deep who recently received his Wilson Staff Irons custom order and has been sharing his thoughts on the clubs in our forum. Per balls_deep:

“Got my custom order in yesterday. I did 4-PW with C Taper limited black in 125g S+ straight in. Unfortunately the only X stiff on the fitting cart was X100, so I had to take a guess and use the MP20 head to test the C Tapers. Hopefully Wilson gets this sorted out as it’s not ideal for those in this bracket of club.

Anyways we are snow-covered here, but we have a range with heated bays, so I was able to test outdoors with a swing caddie for rough yardages. Ball speeds were very consistent, and flight was exactly what I’d like to see. The clubs are as soft as my MP20 were with a bit more sizzle off the face. The long irons are very small but quite easy to hit. Only drop off if you put a properly terrible swing on it and nothing will save you then.

I found them very easy to work up and down or draw/fade. I struggle to fade irons, but with these, it feels like you just think the shot and it happens. Overall fantastic first impression and great build. I’d like to see these in a few more bags as they are criminally underrated. I will update this thread when I head to Florida on the 1st of Feb.”

Along with sharing his informative impression, balls_deep has also posted some great shots of the clubs in the thread which you can check out here.

  • bvanlieu: “Just a timeless design. Diamond edges are classy…reminds me of my set from the late ’80s. I still hit my 8i at the range occasionally. “
  • braincramp52: “They are first class all the way. I’m so pumped for some nice weather to come our way.”
  • rxk9fan: “As good looking as any iron out there. I wish I had a place to test those….like I need to try one more iron set. BUT those are killer for sure!!”
