UST Mamiya Dart V iron shaft review – Club Junkie Reviews
Recently, graphite iron shafts have grown in popularity as technology has taken giant leaps forward. The old thoughts of graphite being too soft, too high launching, or too inconsistent have gone by the wayside. This new batch of graphite iron shafts has been played by all levels of golfers, from players who do need help with launch and spin to professionals who are looking for added control.
Today, we’re taking a look at one of these “new graphite iron shafts.” UST Mamiya Dart V irons shafts come out of the company’s TSPX Lab that creates the most cutting-edge designs and uses the latest materials.
Check out the full review on YouTube below or on any podcast platform.

UST Mamiya’s Dart V shafts are designed around Dual Action Recoil Technology that makes sure the entire shaft flexes consistently for much tighter shot dispersion. The Dart V shafts are offered in 90, 105, and 120-gram weight options to fit a wide range of golfers. UST Mamiya also has very tight tolerances and quality control to ensure that every shaft is the same in the set. Utilizing Torray M40X carbon fiber gives the engineers a material that is 30% better tensile strength and gives the shafts better feel with less harsh vibration.
I went with the Dart V 105 F4 (stiff) shafts as I have found more success with lighter shafts as I have gotten older. Building these shafts up with a set of Vega Mizar Tour heads was very easy and didn’t take a lot of tip weights. I think the 7-iron needed a small 2g tip weight and the rest were installed without any weight at my desired D1 swing weight at standard length with standard size grips.

Out on the course, the first thing I noticed was how tight the Dart V 105 feels. Every swing feels like the shaft is under complete control, no matter if you take a partial or went after it. Stout is a great term for the shafts as they definitely play true to flex, but they aren’t harsh feeling. While the Dart V plays stiff, it still does a good job of reducing vibration and keeping joints or injured body parts free from additional shock.
You can feel the shaft load during the transition to the downswing, but it has a stiffer feel of less flex than some other graphite shafts. Some players like this boardier feel and will get it with the Dart V. Feel at impact is similar to the loading where you are going to feel some kick at the bottom of the swing, but it won’t be as aggressive as other shafts. On center strikes the Dart V offers a very solid feel with great, soft feedback. When you mishit shots with these shafts you get immediate feedback with some additional vibration that feel players will really like. The mishits aren’t too harsh on the hands but still let the head give you the louder click that your ears will want.

Ball flight for me was lower than I expected with UST Mamiya listing the shaft as more mid-launch. I would consider my launch with the Dart V mid-low launch with a more penetrating flight. Better players will like the ability to flight shots, with any club, higher or lower in order to get the ball close to the hole. The penetrating flight helps in windy conditions as it offers a stable trajectory that doesn’t waver from your aiming point.
Shots that you mishit off the toe or heel go pretty straight and you don’t see big curvature that causes you to really miss the green. Most of those misses come off the face fairly straight and leave you with a fairly easy chip or pitch shot to the green. Distance control is consistent and repeatable as I found on the range that well-struck shots have a very tight carry distance window and I have yet to see some wildly long or short shots show up.

Overall, the UST Mamiya Dart V iron shafts are solid options for players who are very particular about performance. Like other shafts among the new breed of graphite iron shafts, the Dart V delivers the type of shots you need when you need them.

Bettinardi The Antidote SB3 and SB5 putter review – Club Junkie Reviews
Bettinardi launched The Antidote putters at the end of 2024 with the SB1 & SB2 models. It was their first jump into zero-torque putters and brought that solid Bettinardi feel to the hottest trend in putters. So at the end of 2025, Bettinardi expanded the line with two more models, the SB3 and SB5 putters, in order to appeal to more golfers. I have gotten to roll both models and think they are great in their own ways.
You can listen to the full review on the Club Junkie podcast, streaming on YouTube or any podcast platform — and be sure to follow on Instagram.
Both Antidote putters have faces milled from 303 stainless steel for a soft, solid feel. The faces feature Bettinardi’s signature F.I.T. Face milling, which removes 55 percent of the face material for a soft, responsive feel. Bettinardi then uses its Diamond Blast to finish the face, reducing glare and creating a durable, great-looking finish. The shafts are installed into the center of gravity of the putter head and feature a small amount of forward shaft lean. This gives each Antidote putter Simply Balanced Zero Torque to keep the face square to the target during the stroke.
The Antidote SB3
When I got the box with both putters, this was the one I was most excited for. Being a long-time fan of “fang” style putters, this one just jumped out to me as the one I need to try. Personally, the silver face and Sapphire Blue as the contrast between the two is another way to make sure the putter is aligned towards the target. This putter frames the ball really well between the fangs, or wings, on the back of the putter and the twin white sight lines that run down them. Getting this SB3 lined up to your target is easy and quick, so you can feel more confident as you are about to get that putt rolling.
The feel of the F.I.T. Face is nice and soft with just enough click to let you know the quality of your contact. While it isn’t something Bettinardi claims, I feel like the F.I.T. Face puts a nice roll on the ball, and you don’t ever encounter hopping or skipping as the ball starts out. My favorite way of explaining the feel of a zero torque putter going through the stroke is the feeling of the face pulling itself through impact. To me, the SB3 has a really stable feel, and it doesn’t want to be manipulated through the stroke. The SB1 might be the most stable feeling, to me, out of all The Antidote putters but the SB3 would be a very close 2nd place. If, and when, you strike the ball out on the toe or in the heel, you will have a feeling of the SB3 not wanting to twist and keeping the ball on line. If you are looking for a zero torque, high-MOI mallet, with great feel and sound, then The Antidote SB3 could be a great option to try.

The Antidote SB5
There are a lot of golfers who would love to try a ZT putter but just don’t love mallet putters. Thankfully, there are some really cool options out there, like The Antidote SB5 putter. To me, this is a really classic-looking putter from address with clean lines and a familiar look that should appeal to the more traditional golfer. Just like the SB3, you get a phenomenal-feeling putter, with both pieces precisely milled from 303 stainless steel. The triple site lines, one on the topline and two on the flange, again work better than I expected with this head shape, and I got comfortable with them fairly quickly.
I typically like ZT putters that feel super stable, but this SB5 seemed to fit my stroke right out of the gate. Players with more arc in their stroke might find the SB5 as something that feels more natural to them, as it will allow you to rotate it just a little more than you can with a traditional blade putter. Even with that, I feel the SB5 was really easy to square up, and I was never searching to find consistency in that. Miss hits with the SB5 were also pretty good. Shots off the heel stayed very straight and had a good, soft feel, while shots struck on the toe felt a little more vibration. Interestingly, when I did miss putts, I noticed that I missed more putts left with the SB3 and more right with the SB5. As I have spent more time with each putter, I have fallen more in love with the SB5, which is a little surprising to me. It has just become a comfortable option to use after a few years of gaming.

Bettinardi continues to excel in its ability to engineer and mill some of the finest putters you can get your hands on. With the SB3 & SB5 additions to the zero torque line, I think they have really widened who can and will play these style putters. If you have tried ZT putters in the past but haven’t found the right one due to the fact that they don’t live up to expectations, then maybe one of these Bettinardi putters can be The Antodote!

SeeMore SBx & SKx zero-torque putter review – Club Junkie Reviews
SeeMore has had a long history of making precision putters. The company gained worldwide fame after Payne Stewart won the 1999 U.S. Open with one. SeeMore’s most famous putter is the FGP Blade, which Zach Johnson used to win the Masters and the Open Championship.
SeeMore is also the creator of a unique, simple, and very effective alignment aid in their Rifle Scope Technology. RST is the use of a red oval and two white lines on the heel of the putter. When the putter shaft, or hosel, covers the red dot and you can only see the white lines on either side of the shaft, then you know the putter is lined up square. SeeMore is now adding another technology to its putter lineup, zero torque.
You can listen to the full review on the Club Junkie podcast, streaming on YouTube or any podcast platform — and be sure to follow on Instagram.

The SBx and SKx putters are the latest additions to SeeMore’s lineup. Zero-torque putters are probably the most significant and hottest segment in golf right now. The design is based on installing the shaft into the putter head’s center of gravity so the toe points up when you set the putter on a table to hold it without restriction. That balance keeps the face square to the target throughout the entire stroke, eliminating the need to square the putter face like you have to do with traditional putters. Now, this isn’t going to turn you into a tour pro, but for many golfers, it can help them consistently get the ball started on the intended line.


SeeMore did a great job with the putter’s looks, keeping it simple without straying from what they do best. The platinum color face is milled from stainless steel for a solid feel and feedback to the golfer, while the body is precision-milled from a block of aluminum. I like the contrast of silver and black as that divide gives my eye an additional alignment aid to make sure I am putting the ball at the hole, or target.
The SBx is going to have a boxier, more straight and sharp look from address with straight wings that extend back from the body. Some golfers will like that look for framing the ball in combination with the single white sight line on the flange. If you like a little softer and more rounded look, then the SKx fits the bill with more rounded fangs that taper inward to give a more compact look at address.
SKx also uses a single alignment line on the stainless topline, and if you look closely, there are two milled sight lines on the back flange that aren’t painted. If you want a little more to look down at, then you could probably fill them in with white paint pretty easily.
Both putters use SeeMore’s RST alignment, and I do have to say it is a simple yet effective way to ensure the putter is lined up correctly. Usually, if I am testing out two zero-torque putters at the same time, one of them stands out as easier to line up or get rolling on the right start line, but these two were equally matched. Lining up putts and starting them on the intended line are easy and repeatable.

Sound and feel are very important when it comes to finding the putter, as it is the voice that speaks to you. I was really impressed, and so was another WRX staff member, by how soft both the SBx and SKx putters are. The first putts were right out of the box on the office carpet, and we both looked at each other with big smiles! The horizontal milling lines on the face provide a soft feel at impact, and the sound is excellent and low-pitched. Not clicky at all, but you still get a good sound with it that is easy to recognize where you hit it on the face.
Being zero torque, the putters have a good feeling of the face staying square through the stroke. They both are a good mix of highly stable feeling and have the ability to move with an arching putting stroke, also. While they may not have the strongest feeling of the face pulling the head through impact, they should be more versatile, as many golfers find success with them.
I still feel very confident when putting with these that the ball is going to come out on its intended line. I have found that with some zero-torque putters, I tend to have a ball that misses left of the hole or target, and I didn’t find that the case with either the SBx or SKx models. I was really impressed with how consistently I was rolling the ball at the target, and I think the heavy focus on the RST allowed me to avoid overthinking other putting thoughts and swing freely.
Overall the SeeMore SBx and SKx are just solid zero torque putters with a more classic shape to them for players who find zero torque hard to look at. The milling and finish work from SeeMore are fantastic and it shows through the performance.

Sugarloaf Social Club x Makino Tour 3 putter review – Club Junkie Reviews
Most of us know Sugarloaf Social Club (SSC) as a clothing and accessory brand that has been leading the way in golf fashion and lifestyle since 2011. Ian Gilley is the founder of the brand and has created some amazing products, primarily in the soft goods category. While clubs have not been the focus of SSC, there have been some limited collabs in the space before working on the Tour 3 putter with Makino.
Makino is a Japanese golf brand founded by Shohei Nomura, an industrial designer based in Tokyo. All Makino’s products are made in small batches where precision and craftsmanship are the most important factors.

To be completely honest, I saw the putter on the Sugarloaf website and wasn’t blown away. When taking the putter out of the box, my mind changed, as the quality of the putter and classic look don’t come through with online pictures.
At first glance, the putter appears a little chunky, with larger shoulders that are very defined near the back cavity area. The bumpers are clean and a good blend of rectangular with softened edges. The topline is definitely on the thicker side, but for some golfers, like myself, it can be used as an additional alignment aid to ensure the face is square to the target.

A single sightline is machined into the flange and filled with white paint, creating a simple and traditional look. A shallow milling pattern is used on the face, featuring the model name and the “S” of Sugarloaf on the heel. The little details like the “Play or Perish” motto on the L-neck are excellent touches that let you know this isn’t a mass-produced putter. 

On the grip wrapping, I was surprised to see there is a sticker that says this is an un-plated putter and could rust…but the putter is made from stainless steel? Now I am not a metallurgist, but a search on the old Google machine told me that SUS303 stainless steel uses materials in the alloy, like sulphur, that make it a little more susceptible to corrosion if you aren’t careful. No rust has shown up yet, but I guess that explains it.
On the green, this putter offers a much softer feel than I and a coworker expected from the face milling. SUS303 and the thick face create a really nice feel and sound! The putter is still responsive, however, and you will get good feedback on putts that you don’t hit on the center of the face.
The putter’s sound is also softer, with not really a click but a more gentle knock as the ball leaves the face, even with a firmer ball like the Pro V1x. Ball speed is consistent and repeatable, and while there is no real high-tech engineering in this head, it performs well enough on mishits. Distance drop off from putts off the toe and heel aren’t massive, and there is still a decent chance you get that ball to the hole.

At the end of the day, this putter is much more than I thought it was going to be. The shaping and quality of the finish are phenomenal, showcasing the skill of Makino and the creativity of Sugarloaf. Traditionalists will love the classic look, while feel players will be impressed by the softness and responsiveness the Sugarloaf Social Club x Makino Tour 3 provides.
