2024 Mitsubishi Diamana BB Shaft – Blue Board is Back

The celebration of twenty years of Diamana continues, with Mitsubishi Golf unveiling the second part to the all-new version of the legendary lineup. It makes sense that the brand came with the WB (White Board) first, as it has long been the first design people think of when they hear “Diamana”, but as soon as it was released, the clamoring for the BB was immediate. Previously, we were able to give a full review on the Diamana WB (here: Mitsubishi Diamana WB Shaft Review – The Hackers Paradise) and now, on the day the 2024 Diamana BB is officially released, we are not only bringing you all the details, but also one of the first full reviews in all of golf. 

Quick Take – 2024 Diamana BB

The Blue Board is back. As with the WB, when it comes to the BB, Mitsubishi has managed to up the ante by taking the same legendary profile that is known and loved, but amplify it with new materials and technologies. On the course, the BB is exactly what you would expect, fluid without being loose, and lives up to the mid-mid profile designation. 

2024 Mitsubishi Diamana BB – Design

For 20 years now, Diamana has been the crown jewel of Mitsubishi Golf. When it comes to performance and feel, the company truly believes they are at the top of the game with this family of shafts. However, they also want it known that although the designations of these new Diamana shafts is the same historically with WB being “low-low” and this BB being “mid-mid”, this is not just a rehashed release. No, this is taking the DNA of the “boards” and modernizing it. 

In this 6^th generation BB, new meets classic, beginning with the matte black finish and retro cosmetics, including the illustrious “flower band” below the handle. Just as we said about the WB, the BB is one of the best looking driver shafts we have seen in some time, it’s clean but also flashes in the right ways. Plus, there is something cool about being able to immediately tell visually what someone is playing, and the flower band with classic blue backed Diamana logo absolutely brings that recognition to this release. 

The new Diamana BB profile is classified by Mitsubishi as Medium+ under the hands and mid-section, then Medium in the tip section, and is also being offered in the traditional 53/63/73/83 weight categories. This leans into the smooth feel which the BB is historically known for. However, according to the company, that has been taken up a notch via improved materials and processes. 

As with the WB, the BB is implementing “Xlink Tech” which is another Mitsubishi developed resin system. By reducing the amount of resin necessary in creating a composite shaft, they are able to use more carbon fiber volume. That increase not only means more feel, but also more strength and durability. Combined with that, the 6^th generation Diamana’s also use high-modulus 46-ton angle plies to lower torque and increase stability as well as super high-modulus 80-ton Dialead Pitch Fiber in the butt section of the shaft for better energy transfer. 

In the end, Mitsubishi believes they have created a better Blue Board which is smoother than ever, but with a new level of stability and downrange consistency. 

2024 Mitsubishi Diamana BB – Performance

As mentioned, not only are we bringing all the details for the BB release up above, but THP was also able to get the new design in hand and put it to the test. More than that, four of our community members were able to as well, and they will be bringing their long-term feedback to the THP forum, so be sure to keep an eye out for that. 

This review was done with the Diamana BB in 73X paired with the Callaway Paradym Ai Smoke Triple Diamond head at 9.0 standard. Having also done our previous review on the WB, there were many curiosities entering into this, specifically because once upon a time the Blue Board was a go-to for me, specifically in a lower spinning driver head like what this testing was done in. 

The standout aspect immediately here was that classic BB ‘feel’, which personally I prefer to use the term flow. Throughout each swing, there is a flow present which absolutely differentiates it from the WB. Interestingly when it comes to that comparison, however, is that this 6^th Generation WB is strikingly smooth, more than any previous iteration I had swung. Well, the same can be said about the new BB. Regardless of how I went at the ball, that feel/flow was present, be it high-speed, mid, or even user error driven swings. 

While feel is great, it is the flight, spin, and dispersion characteristics which everyone cares about the most. Both on the course as well as on the launch monitor, the 73X BB proved to be every bit the mid-launch shaft it claims for this reviewer. When it comes to the data you will see below (which comes from a set of ten swings with the two biggest misses thrown out), it checks the boxes. Now, some may see the launch and spin as a bit on the lower side to be called mid-mid, but keep in mind this was with a 73 version of the shaft. 

What is the conclusion? This is going to be a very popular, and very versatile, shaft for Mitsubishi. While this review was done in a driver, it is obvious that there are ample fairway wood applications possible as well. In fact, when you combine the BB with the WB, the fitting possibilities are significant. Smooth, reactive, accurate, and fantastic looking, the 6^th version of the Blue Board lives up to the hype. 

The Details – 2024 Diamana BB

Mitsubishi is releasing the new Diamana Blue Board worldwide beginning today through fitting centers and custom order options across the world. While nostalgia alone does wonders, it is only when a brand takes that and molds it with modern performance that you strike onto something more, and that certainly appears to be just what is happening with Diamana right now. The price point for the BB will be set at $400.00.
