Tour Edge unveils new Exotics C721 and E721 irons
Tour Edge has today unveiled the all-new Exotics 721 Series irons: the C721 iron and the E721 iron.
The Exotics 721 irons are designed to provide every level of golfer two extreme distance irons and are led by the brand’s new Diamond Face 2.0 and Vibrcor technology for irons that combine full-face forgiveness and ball speed with optimal sound and feel.

Speaking on the technology featured in both sets of irons, Tour Edge founder and President David Glod said
“Vibrcor is a new technology that enhances speed and feel in a major way. With the dual placement of Vibrcor inside of the hollow-body pocket of the C721 and the undercut pocket of the E721, we’re able to provide the best of both worlds; perimeter weighted forgiveness and distance with the feel of a forged muscle-back.
“We’ve also brought Diamond Face technology to irons for the first time ever with this release. We were able to cover the entire iron face with up to 100 diamond shapes behind the face in our thinnest iron face ever produced.”

Tour Edge Exotics C721 iron

Designed as a players distance iron, the new C721 from Tour Edge features a smaller, more classic shape, more traditional lofts, and a thinner topline.
The Exotics C721 iron consists of an ultra-light TPU (Thermoplastic Polyurethane) injected into the hollow-body pocket to create new speed-inducing and feel-enhancing technology: Vibrcor.

The proprietary Vibrcor TPU is strategically placed in two places within the iron in a bid to create a feel-enhancing internal technology with perimeter weighting around the entire clubhead aimed at providing maximum forgiveness and power off the face.
Vibrcor performance TPU is injected into the hollow-body cavity and works in partnership with an extremely thick, yet light Viebcor layer designed to further aid the clubhead’s feel and produce faster ball speed off the face while dampening shock at impact.

The hollow-body design with dual Vibrcor infusions delivers a low CG (center of gravity), which bids to aid with launch, distance, and overall playability. It also adds 12 grams of weight to the low end of the clubhead, increasing deflection, which is designed to create an explosive spring effect off the face.
The Exotics C721 iron features full-face Diamond Face 2.0 technology; the first time Tour Edge has employed Diamond Face technology in an iron.

There are a total of 92 diamond shapes that cover the entire face of the C721 iron. The different diamond shapes of variable face thickness behind the face act as mini-trampolines to create faster ball speeds and expand the sweet spot to the outer areas of the face.
Diamond Face 2.0 features three different thicknesses in an interweaving pattern and features a face thickness reduction of 29 percent.
This increase in Diamond Face coverage to the extreme heel and toe is designed to dramatically increases ball speed on off-center hits. The decrease in the face’s overall thickness also saved five grams of weight that was relocated to the lowest part of the clubhead.

The iron features a two-piece cast body with a forged high-strength military-grade maraging steel face that is plasma-welded onto a 17-4 stainless steel body.
This ultra-high-strength steel is used in aerospace, with landing gear, helicopter undercarriages, slat tracks and rocket motor cases and other applications requiring a high strength-to-weight material.
The L-Cup Face acts as a hinge designed to improve accuracy and protect ball speed on off-center hits.

A thinner leading edge on the new iron aims to provide a dramatic spring-effect throughout the face for added forgiveness on miss-hits either off the toe or the heel. The hollow-body iron design of the Exotics C721 iron aims to provide the best in perimeter weighting.
The hollow body design creates distance and forgiveness, and when combined with Vibrcor, it bids to achieve a player’s distance iron with the feel and control of a forged iron. In addition, the Notch Hosel on the iron head allows for easier bending +/- 3-degrees for enhanced custom fitting, while SpeedTested shafts allow for optimal shaft fitting.

Tour Edge Exotics E721 iron

The extreme game improvement distance Exotics E721 Iron is designed with a larger footprint and a wider sole that utilizes hollow-body Vibrcor and Diamond Face 2.0 technology.
The Exotics E721 Iron utilizes a high-grade TPU strategically placed in the deep 360-degree undercut pocket to create the new speed-inducing and feel-enhancing technology: Vibrcor.

A second TPU is encapsulated in the steel-covered cavity insert that works in partnership with the extremely thick, yet light Vibrcor layer to further aid the clubhead’s feel in design to produce faster ball speed and to dampen sound and shock. This dual Vibrcor treatment aims to create an iron offering the feel of a full-flush cavity iron in a sleek, extremely long, and forgiving iron head.
The E721 iron also features Diamond Face 2.0 technology with 103 diamond shapes to the extreme heel and toe of the thinner face aiming to dramatically increase ball speed on off-center hits.

The E721 design is a 1-piece high-strength steel body with a 360-degree Undercut Design aimed at lowering the CG to produce a higher launch and increased face flexing, ball speed and overall distance across the entire face.

Extreme toe weighting on the Exotics E721 iron elongates the sweet spot in design for added forgiveness. Simultaneously, the lower and deeper CG allowed the E721 irons to be power-lofted to create distance and lower spin rates while achieving the same launch characteristics as a standard lofted iron.

The notch hosel allows for easier bending +/- 3 degrees, while each shaft has been SpeedTested for optimal custom shaft pairing.

Project X launches Titan Yellow wood shaft, pivotal to Clark’s CJ Cup victory
Wyndham Clark made a pretty significant change ahead of his CJ Cup Byron Nelson victory. A change in driver shaft helped the 2023 U.S. Open champion return to the winner’s circle on the PGA Tour Sunday in Dallas.
Clark was one of the first players on Tour to try out and game the new Project X Titan Black shaft. He added it earlier this season on the TaylorMade Qi4D driver as he was able to consistently hit the spin numbers he was looking for.
But entering TPC Craig Ranch, Clark wanted even more performance off the tee, more specifically with his accuracy.
Step up, Titan Yellow.
Built with a specialized counterbalanced design (a higher balance point), Titan Yellow is engineered for modern driver builds, helping offset heavier heads and giving players more room to dial in swing weight, head mass and overlength setups.
The result is a low-launch, low-spin profile designed for clubhead control, speed, and stability for the more aggressive swinger. The Titan Yellow delivers a responsive feel in the hands with the tip stability needed for the faster swingers on tour.

“With the balance point change, we may see a little bit in higher launch, a little bit more spin, but these are still definitely a low, low profile all the way through,” Bragg added. “Biggest difference is that balance point change from Yellow. So potentially the builder last week wanted to optimize ball flight a little bit more, maybe a little bit more spin to hold the start line.”
Titan was engineered right in Project X’s headquarters in San Diego, California, and uses a unique EI profile as well as a new Synex Technology to provide Tour-level performance to those players who need it.
The EI profile features a handle section that is more flexible to give players the feel of the shaft loading during the swing. The mid and tip sections are firmer to add stability to the shaft for better dispersion.
Project X created a new Synex Technology to reinforce the shaft’s outer layers. Synex is a multi-axial carbon fiber that is used in the handle and mid-section to increase hoop stiffness and reduce deflection. This new carbon technology improves energy transfer and should help generate additional ball speed.
Available on Tour, the Titan Yellow comes in 60, 70, 80 TX flexes.

Mizuno’s Signature and Modern Series irons: Which iron should you be playing?
The iron line from Mizuno Golf has recently evolved to maximize its offerings for golfers of all levels. This new Mizuno Pro Modern series sits between the classic Mizuno Pro Signature Series and the technology-packed Mizuno JPX925 lines. Mizuno engineers took some DNA from each side to create the Pro M-13 and Pro M-15 irons, so you can get a lot of everything without compromise!
When you look at the refreshed Mizuno iron line, the Pro Signature Series is made up of the S-1 and S-3 irons that show off the traditional side of Mizuno iron creation. Both models are designed and crafted for feel and precision with shot makers in mind. Players who cherish that classic Mizuno forged feel with love the feeling of being more connected to the iron for impact feedback and precise ball control. Shaping and consistency from shot to shot are what the Mizuno Pro Signature Series does so well, like a finely tuned sports car on the track.

Mizuno took the traditions from the Pro Signature Series and added a good dose of performance to create the new Pro Modern Series with the M-13 and M-15 irons. Golfers will get, as they expect, the soft, forged feel that Mizuno’s Grainflow Forged HD process provides, but will also experience a more distance-driven design. Both the Mizuno Pro M-13 and M-15 will offer higher flight, more forgiveness, and, of course, more ball speed. Mizuno used multi-piece designs to create thinner faces and move weight in the head for added performance and stability. These more progressive irons combine that traditional feel and look with technology packed under the hood to fit a wide range of golfers.

Distance
Both the Pro M-13 and Pro M-15 are engineered with distance in mind. The M-15 is, of course, the leader in this group for ball speed and distance, thanks to its Contoured Ellipse face with Cortech technology. This multi-thickness face not only increases ball speed but keeps that speed consistent and removes hot spots from the face. Players will continue to maintain control of their shots while hitting less club into the greens. With the M-13, Mizuno engineers also used Contour Ellipse technology on a face that is 35 percent thinner than the Pro 243 irons. The M-13 delivers a great feel and responsiveness while producing a faster ball speed. Players looking to improve their length while maintaining control over their shots will gravitate toward the Pro M-13.

Forgiveness
When you pick up the Pro M-13, you appreciate the classic Mizuno shaping and compact look, but you don’t think it will be as easy to hit as it is. Off-center shots retain more ball speed than you would expect from a players looking iron. This consistent speed will allow you to still get the ball on the green when you don’t make perfect contact. Mizuno’s use of a Pocket Cavity in the long irons (4-5) and a Micro-Slot cavity in the mid irons (6-8) gives the set a lot of playability and precision. I figured the Pro M-15 was going to be an easy iron to hit, and I was not disappointed at all. A Multi-Material Hollow Construction in the longer irons (4-8) combines heavy tungsten weighting for optimal launch and stability. You can make contact farther out on the toe or near the heel and still see a shot with good launch and very little curve to it. Like the M-13, you can expect consistent ball speed across the entire face that will help you hit more greens.

Sound & Feel
When you hit a Mizuno iron, you expect a level of feel and sound that is pleasing to your senses. Both of these irons embody the attention to detail that Mizuno has demonstrated over decades of clubmaking. Both irons are soft due to the Grain Flow Forging process and offer a solid sound at impact. The Pro M-13 is a touch softer to my hands, but not by much, and I think most players who have hit distance irons will be impressed with how good these are. Even misses that are out in the toe or low on the face don’t generate harsh sounds or feel in your hands and ears. Solid strikes give you that swoosh and thud that make you love golf and playing forged irons.

The E721 6 iron has the loft of my 4 and since the target player would probably have difficulty hitting anything less than 24* from the fairway, would probably wind up with more irons with letters than numbers. Loft jacking is getting ridiculous!

Really enjoy all the Golfwrx content. However can never understand why someone with golf experience writing these articles do not include a picture of what irons (or any club they are writing about) look like at address? It’s the most important photo and left out most of the time.

Pretty mediocre offerings
What is their advantage over established OEM’s with this offering?….not much that I can see
A non event launch of a middle of the road generic iron…

“…is designed to dramatically increases ball speed…
If you want to be taken at all seriously please provide supporting data. (GolfWRX should demand it.)
“…with the feel of a forged muscle-back.
Anybody who is interested in these most likely has no idea what a forged muscle back, centre-face strike, feels like.
I continue to be disappointed by Easy’s decision to cap the journalist’s salaries at such a low level.

Looks like a generic catalogue club builder set. Shocked they still have that dismal logo as well.

As someone with TEE irons, a driving iron, and 3 wood, I’m obviously a fan. But Jesus, whoever is in charge of design the last 2 years needs to go. They were on a roll with the CBX lineup, but for some reason they killed it and then they went full on box set from a visual standpoint. That logo is butt ugly. Forward this to David Glodd.

Yep the visuals definitely have the “$150 amazon.com generic brand set” look to them.
