UST Mamiya LIN-Q M40X Blue Shaft

One of the great surprises that really impressed me last season, as well as many others, was the LIN-Q shaft lineup from UST Mamiya. While UST Mamiya is certainly no stranger to quality golf shafts, there was something almost inexplicable about these LIN-Qs. They just felt and performed amazingly, and the Purple was easily one of the best looking shafts in the market. Fast forward and 2021 introduced three new shafts utilizing a new combination of materials evolved from the original LIN-Q foundation . The UST Mamiya LIN-Q M40X Blue shaft is the mid launch, mid-low spin option in the new ultra-stable M40X lineup.

The Looks

Based on the name, you can safely assume the UST Mamiya LIN-Q M40X Blue has a base coat of a shiny metallic blue. Around the mid section is an overlapping white LIN-Q logo. There’s a subtle black pattern underneath the white LIN-Q branding that’s reminiscent of the “high tensile modulus” M40X utilized in the shaft which we’ll discuss later.

How Does it Feel?

The big difference in the M40X generation and the original LIN-Q shafts is that UST Mamiya introduced a new fiber for more stability. This generation combines the Q-fiber used in the original shafts with the new M40X material which is much stronger but doesn’t feel boardy and lifeless. As a result, the LIN-Q M40X Blue has a an extremely firm and controlled feel, but is very smooth, responsive, and player friendly even at a higher speed with an aggressive transition. Out of the three LIN-Q M40X shafts, I found the Blue to have the most “universal” feel that will likely appeal to and work for the widest range of golfers.

On-Course Performance

The UST Mamiya LIN-Q M40X Blue not only feels the most player friendly out of the bunch, but also performs as such. Installed in my trusty Tour Edge C721 driver, this shaft was automatic with around 13º of launch and 2400-2500 spin. More impressive, however, was the ease of control. As mentioned earlier, the new M40X provides more stability and is easier to control, especially with a more aggressive swing. M40X actually improves the “lateral stability” which essentially means the shaft keeps its cylindrical shape better. This makes finding the center of the face easier, but it also transfers more energy back into the ball. By not spending energy “trying to return to its natural shape”, the shaft is able to transfer that energy back into the ball to provide more power at impact.

Final Thoughts – UST Mamiya LIN-Q M40X Blue

I honestly thought the original LIN-Qs’ shoes were going be tough to fill, but UST Mamiya did a great job with this generation. The original LIN-Qs were notable due to their stable feel and reliable control, in my opinion. UST’s M40X version of the LIN-Q is similar, but just…better. The Blue specifically is easy to hit, very stable, and a versatile graphite shaft. If this sounds like the shaft for you, the LIN-Q M40X family is exclusively available for fitting at any UST Mamiya TSPX dealer.
