Mitsubishi MMT Iron Shaft Review: The Perfect Gateway To Graphite

The perception that graphite iron shafts cannot withstand aggressive swing speeds or deliver tour-level control is rapidly becoming a relic of the past. Mitsubishi tackles that skepticism head-on with the MMT series, integrating a specialized metal mesh into the tip section to blend plush vibration damping with steel-like stability.

We put the shaft through our standardized launch-monitor testing to see whether its flight consistency and feel live up to the hype.

How We Test Shafts

All of our shaft testing is conducted using the same TaylorMade Qi35 core head driver set to a precise 9 degrees (measured), with each shaft cut to an exact length of 45.5 inches, fitted with a Golf Pride Tour Velvet 60R grip. Furthermore, all testing shots are struck from a white castle tee to ensure consistent tee height during testing.

The data is collected and recorded using a Foresight Sports GC3 launch monitor and TaylorMade TP5x golf balls.

Controlling these potential variables allows me to draw accurate and direct comparisons and form a clear picture of each shaft's performance and feel characteristics.

Mitsubishi MMT Iron Shaft Review: Technology

The MMT (Metal Mesh Technology) distinguishes itself by utilizing a unique composite construction. Mitsubishi integrates a specialized metal mesh in the tip section of the shaft to significantly increase stability and consistently produce the center-face strikes needed for elite iron play.

The shafts are available in both taper-tip (featuring a premium gloss finish) and parallel-tip (featuring a matte finish) options. The fitting window is impressively vast, with weight and flex options scaling all the way from a lightweight 55g A-flex up to a robust 125g TX-flex.

Mitsubishi MMT Iron Shaft Review: Performance

For my testing, I utilized the 105 TX model. Despite this being significantly lighter than my normal Dynamic Gold X100 shaft (which sits at approximately 130 grams), the MMT provided incredible stability and consistency of flight.

I will admit that I was marginally struggling to find the consistency of strike I would have liked to begin with, but this was purely and simply down to the fairly drastic weight change from what I was used to. Adding around 12 grams of lead tape to the base of the grip completely transformed the consistency of strike for me, leading me to believe that the 125-gram version could be absolutely perfect for me, and based on how much I enjoyed the feel and performance, Mitsubishi - I may be reaching back out!

From all of the graphite iron shafts I have tested to date, I would have to say that the MMT feels the smoothest to me. That said, don't confuse smooth with soft; they provide more than enough stability for me, and I am around or even slightly above PGA Tour average speed. One or two other graphite iron models I have dabbled with have popped the ball flight up a touch, but not so here.

Controlled, penetrating flights were the order of the day for me, which is something I am always craving.

I have long been a proponent of the feel and vibration absorption properties of graphite in irons, and nowhere have I had this confirmed more than in the MMT model. Off-centre strike vibrations are significantly subdued, diffusing the harshness often associated with mishits. Think of it kind of like the silicone vibration dampener you find on a tennis racquet.

The consistency of launch and spin numbers once I had found an appropriate weight was very reassuring, and a total non-negotiable for me.

Finally, I very much enjoyed the minimal graphics and branding Mitsubishi has utilized on the MMT. The minimalist, monochrome design will pair well with any head and shaft combination.

Mitsubishi MMT Iron Shaft Review: Verdict

If you are looking to make a first dalliance into the world of graphite iron shafts, the Mitsubishi MMT feels like a superb place to start due to the compelling combination of feel and stability.
