Every once in a while, a new shaft earns buzz on Tour and among everyday golfers at the same time. That’s exactly what’s happened with the UST Mamiya LIN-Q PowerCore. It’s already helped PGA Tour winner Ben Griffin become one of the best drivers on Tour, and THP’s ShaftUp! members who tested it early are saying the same thing.
“This one feels different.”
After more than a year of Tour testing, countless prototypes, and two THP ShaftUp! Experiences where our readers got early access, the PowerCore family is finally ready for launch. This one doesn’t just mark another addition to the LIN-Q lineup. It represents a step forward in how energy transfer, stability, and feel are engineered into a modern golf shaft.
When UST Mamiya says, “The Game Changer,” they aren’t exaggerating. PGA Tour player Ben Griffin has already proven that statement true with three wins in 2025 using the LIN-Q PowerCore. Before putting it in play, Griffin was statistically a below-average driver on Tour. Since making the switch, he’s jumped into the elite tier in both accuracy and total driving performance. One player doesn’t define a shaft, but his transformation is strong validation of what the technology can do at the game’s highest level.
The UST Mamiya Lin-Q PowerCore Design
At its heart, PowerCore is a new way of thinking about shaft construction. UST’s engineers combined their exclusive Q-Ply Material with a Nano Resin Matrix, creating a structure that is both stronger and more responsive. Q-Ply reinforces the hoop strength of the shaft, meaning it resists deformation during the swing. Less deformation equals more consistent face delivery and tighter dispersion. The Nano Resin Matrix works as the connective tissue, improving how energy moves from the hands to the clubhead. Together, they generate what UST Mamiya calls “Maximum Energy Transfer”, and what players simply describe as effortless power and control.
In testing, the PowerCore consistently produced tighter launch and spin windows than previous LIN-Q models. Tour reps noticed that every shot seemed to live inside a smaller envelope of variability, especially on off-center contact. For fitters, that kind of repeatability is gold. For golfers, it translates into more predictable distance and trajectory from swing to swing.
Stability You Can Feel
There’s a balance between stability and feel that every shaft designer tries to capture. Too rigid, and a shaft can feel harsh and lifeless. Too active, and dispersion suffers. PowerCore finds the middle ground by strengthening the entire structure rather than stiffening specific sections. The result is a shaft that feels alive without being loose.
Players who tested PowerCore at early ShaftUp! fittings described the sensation as “connected.” There’s feedback, but not vibration. The tip section feels controlled, yet the transition is smooth and easy to time. One fitter described the feel perfectly after hitting the LIN-Q PowerCore White 6TX:
“It did not feel overly board or hard to load. There was an activeness to it that felt really good.”
Another tester summed up his experience more simply:
“Loved the feel, loved the ideal launch and spin window, and loved that I more or less couldn’t miss a fairway.”
Those are the words of THP members who had the chance to put PowerCore in play months before launch.
Validation Through the ShaftUp! Experience
For the last several years, THP and UST Mamiya have partnered on the ShaftUp! Experience, a hands-on fitting event that gives our community access to UST’s latest technology before it reaches the market. In 2025, we hosted two of these events, and participants were fit directly into LIN-Q PowerCore by UST’s experts. The feedback was overwhelmingly positive, with many noting improved dispersion and a better sense of control through impact.
“The gains everyone saw at ShaftUp were incredible,” one member commented after testing.
We’ve been part of plenty of shaft tests over the years, but it’s rare to see this kind of consensus from golfers with such a wide range of swing speeds and preferences. It speaks volumes about the design’s adaptability. Whether in the hands of a mid-handicap player or a Tour pro, PowerCore seems to find the same goal: better energy transfer and more consistent performance.
Engineering the Difference
The PowerCore’s improved stability doesn’t come from chance. Its high-hoop design minimizes shaft ovaling, which is the unwanted shape change that happens when a shaft bends under load. By keeping the structure round throughout the swing, PowerCore maintains consistent flex and release characteristics. That’s why shots struck across different parts of the face show less variation in speed and spin.
UST Mamiya’s Nano Resin Matrix deserves equal credit. The nano-level resin evenly distributes carbon fibers, removing weak spots that can compromise performance. It’s the same kind of material engineering you might find in aerospace composites, now applied to a golf shaft. Together, these elements allow the shaft to return to neutral faster and more predictably, which is why Tour reps call it “tighter through impact.”
Tour Performance and Beyond
If you want proof that the LIN-Q PowerCore delivers on its promise, look no further than Ben Griffin. In 2025, Griffin transformed from a talented journeyman into one of the most consistent players on the PGA Tour. Since putting the PowerCore in play, he’s earned three Tour victories, 11 top-10 finishes, and finished 10th in the FedEx Cup standings, his best season by far. Griffin openly credits the shaft with helping him find a blend of distance and accuracy that he hadn’t achieved before. What began as an equipment change quickly became a catalyst for a career shift.
Griffin’s story isn’t an isolated one. The LIN-Q PowerCore has quietly become one of the most-played shafts across professional golf. On the PGA Tour, 14 of the top 100 players now rely on PowerCore in their drivers or fairway woods, and the trend is accelerating. On the Korn Ferry Tour, it’s the fastest-growing shaft model, averaging 49 installations per week, compared to 23 per week on the PGA Tour. That kind of adoption doesn’t happen by accident. It’s the result of measurable improvements in consistency, speed, and control that elite players can see and feel.
For UST Mamiya, this level of validation is exactly what the PowerCore project was built for. The company’s Tour reps describe the launch and spin patterns as “tighter than anything we’ve seen,” while players praise the way it maintains speed even when contact isn’t perfect.
But the story doesn’t end on Tour. UST Mamiya has made it clear that PowerCore was designed to help all golfers, not just those with 120 mph swing speeds. The line will feature multiple profiles (White, Blue, and Red) to match different tempo and launch preferences. Each version shares the same core materials and design philosophy, ensuring consistent stability and feel across the lineup.
LIN-Q PowerCore Profile Overview

Availability and Fitting
Golfers will be able to get fit for the UST Mamiya LIN-Q PowerCore starting January 5, 2026, through authorized fitters and custom builders worldwide. The shaft will be offered in a full range of flexes and weights to suit drivers and fairway woods. Pricing will vary depending on build and fitting options, but expect it to align with other premium Tour-grade shafts in the market.
Those who have already experienced the technology through the ShaftUp! program have a good idea of what to expect: a smoother, more stable feel, improved energy transfer, and a launch pattern that simply holds its line. You can read their thoughts on the THP Forum here.
Final Thoughts
In a crowded shaft market, where every new release promises lower torque or higher speed, UST Mamiya has done something rare with LIN-Q PowerCore. They’ve delivered a measurable difference in performance and feel. Ben Griffin’s success on Tour highlights what’s possible at the highest level, while the THP community’s feedback proves the benefits are tangible for everyday golfers too.
The combination of Q-Ply Material and Nano Resin Matrix has created a design that feels connected, consistent, and powerful. From Tour wins to firsthand success at our ShaftUp! events, PowerCore has already written its own story. It delivers stability that feels natural, energy transfer that shows up on the launch monitor and the golf course. It may have started as a Tour project, but this shaft was built for every golfer chasing consistency.
