The Mitsubishi Diamana TB is the fifth generation of one of the winningest, best-selling shafts in history. Extremely smooth feel. Consistent Feel Design opens up new options for golfers and fitters.
Sequels and follow ups tend to fall into one of two camps. There are some that make you roll your eyes – “Do we really need another season of The Bachelor?” There are others that have you looking at the calendar waiting for the release date. Mitsubishi’s Diamana shafts have always been in that latter category because they find compelling new things to add to some of the best shafts in golf.
MCA dialed up the aesthetic volume on the new Diamana TB. The Diamana branding, in silver on blue, is as big and bold as it’s ever been. Additionally, the transition from bright white to a striking blue will turn heads. Even the blue alone has a layers – the color seems to vary across several shades depending on the lighting.
The signature Diamana flower band is still present, though it’s downplayed with a silver-on-white color scheme. More emphasis is put on the silver “D” logo which sits on a pool of blue near the grip.
The headline with any Diamana shaft, particularly one with their “signature smooth profile,” is smooth. Diamana consistently makes the smoothest feeling shafts in golf, and the new TB is no exception.
For me, the kick starts just below the grip and effortlessly proceeds to the club head. There’s no feel of aggressive loading and snapping, just an unhurried transfer of energy to the ball.
Like the fourth generation Diamana BF [review HERE], the TB has a solid tip section. Even on mishits, I didn’t feel the head twisting or torqueing.
Before I get into my personal experience, I want to explain what’s new about the fifth generation of Diamana shafts. Mitsubishi calls it Consistent Feel Design, and it’s a tremendous concept that eschews the typical salesy junk (“Faster! Longer! Straighter!) in favor of something that will actually help golfers play better.
First, a little background knowledge. In almost every shaft family, when you change weight class or flex, you get a bunch of other changes, too. When you step up in flex, the shaft gets a little heavier, the butt diameter may increase, the balance point may shift. That makes finding the right fit more complicated because it adds more variables into the mix.
With the new Diamana TB-Series, Mitsubishi has 80% less variance in butt diameter, 60% less variance in weight between flexes, and the balance points of the shafts are within 1% for each weight. What that means is that you can isolate variables like weight and flex to find the right shaft more easily.
Now, as for how the Diamana TB-Series performed for me, it was excellent, as expected. Diamana’s smooth (blue) shafts always make me rethink my commitment to low launch shafts, and the TB is no different. In my testing, I found that both the direction and trajectory were extremely predictable. The ball consistently launched on a mid trajectory with mid-low spin. What was most exciting for me was that I saw an uptick in ball speed compared to my gamer.
The fifth generation Diamana TB is available in an enormous range of weights and flexes. At 40 grams, Mitsubishi offers R2, Regular, Stiff/Regular, Stiff, and X. In the 50 and 60 gram categories, the R2 is dropped and the TX flex is added. At 70 and 80 grams, you will find Stiff, X, and TX.
Even with four generations in their rearview, the Diamana TB-Series shafts prove that Mitsubishi still has plenty of tricks up their sleeve. The performance of the Diamana TB has me giving it serious gamer consideration, and Consistent Feel Design will make it a favorite among fitters and players alike.
