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 6th 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.
| SHAFT | FLEX | WEIGHT | TORQUE | KICK |
| Diamana BB 43 | R2 | 44 | 5.1 | MID |
| Diamana BB 43 | R | 45 | 5.1 | MID |
| Diamana BB 43 | SR | 47 | 5.1 | MID |
| Diamana BB 43 | S | 48 | 5.1 | MID |
| Diamana BB 43 | X | 49 | 5.1 | MID |

| Diamana BB 63 | X | 62 | 3.2 | MID |
| Diamana BB 63 | TX | 62 | 3.1 | MID |
| Diamana BB 73 | S | 70 | 2.9 | MID |
| Diamana BB 73 | X | 71 | 2.9 | MID |
| Diamana BB 73 | TX | 72 | 2.9 | MID |
| Diamana BB 83 | S | 80 | 2.8 | MID |
| Diamana BB 83 | X | 81 | 2.8 | MID |
| Diamana BB 83 | TX | 81 | 2.8 | MID |
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 6th 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 6th 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.
| Diamana BB 73X in Paradym Ai Smoke TD 9.0 STD | |
| BALL SPEED | 162 |
| LAUNCH ANGLE | 14.1 |
| SPIN | 2590 |
| PEAK HEIGHT | 33 |
| CARRY | 274 |
| TOTAL | 300 |
| OFFLINE | 9Y R |
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 6th 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.

Another range session where I only had to hit 3 balls with this. All three striped, 155-160 ball speed, straight to slight cut
I feel like a broken record at this point, but man it’s so good.

Only hit driver 4 times on Sunday over 9 holes. Good baby down the middle on two. Turned one over slightly while expecting baby fade, in left rough but pounded a few holes later. Next one did fade and caught a tree and probably fell in water, couldn’t find it, took a drop for pace of play. Last one hammered up the left side basically dead straight. Still not 100% certain about my release point. Much better with the 9* Max-K though. Trajectory is pretty spot on now. Hard to really judge right now with limited play on the cranky left hip.
Took my first swings with the Blue Board last night, albeit a bit rushed. Tonight will have more time to get a feel for it.
Starting from a Tensei Blue 6x and moving to a BB 6x so keeping it in the Mitsubishi family and the profiles do feel similar. There is slightly less firmness in the butt of the BB and slightly more in the mid section. How that translates is it feels like there is a little bit more action at the start of the backswing and a more stable smoothness after the initial move down. Smooth is the word everyone uses with this shaft and I absolutely get it. The Tensei series has a harshness about it; maybe it’s due to material differences or otherwise, but it feels a bit more raw. The BB feels more refined, more stable, like it glides. It could very well be placebo effect in that I know Diamana is a shaft made with better materials, but I don’t care so long as I am finding the center of the face more.
I haven’t seen any real gains yet, but the short session started with a slice on both shafts so that has to be corrected to really pair them side by side. More work to be done tonight, but already loving the feel.
Got in a good chunk of time with the Blue Board and definitely found something. Let’s start with where we are at now:
Tensei Blue 6x struggling a bit with a slice again lately as well as some hitting down on it issues but that’s a me problem more than a shaft problem.
Here are a couple pretty typical drives if not decent ones

That’s all green spin! Slightly high on launch and descent but spin is down and distance is up! Throughout the rest of the session we definitely found something because the final few were green boxes across the board
[ATTACH type=”full” width=”520px”]9377766[/ATTACH]
I am not going to say it’s all the shaft, but the shaft is absolutely helping my swing and consistency. I am finding the center of the face more, I am keeping spin down even on bad strikes, and distance is going up. I think I am going to get along with this beauty for quite some time….but I do kind of want to try a White Board now :censored::geek:
I have a new driver in hand, and I will be pulling the Diamana BB from the Max K and getting a new adapter installed. I went with a Titleist GT3. I have had it for about 3 weeks now. I have hardly any playing time but will be testing the BB in the GT3. They didn’t have the 43 available to hit when I was getting fit so i am excited to try it with this head!
I would think that the head doesn’t matter when you get along well with the shaft, but you never know!
Good luck!
The BB is ready for the GT3 and I pick it up tomorrow. Will be on the range Friday and hopefully get a round in this weekend we will see.
Well, I took my first swings with the Diamana BB in my new GT3 today. It was bomb city I was having a day on the range with everything I touched. I hit the Air speeder 3 times then the BB 3 times. They are very close in performance, but the BB has a different feel to it. I want to say it feels more stable throughout the swing. I also was hitting the BB higher today than I ever have. It was great to see the height and distance I was getting. These were nice high draws. My plan is if I get to play this weekend, I want to play the BB on 9 and the Air speeder on 9 to see the on-course results. I have a feeling my miss hits will be much better with the BB.

I played with the BB in the GT3 today. I hit driver 5 times and only missed 2 FW. One of those shots was just off by about 3 yards and the other shot I pulled it to the left trying to get all I could out of it lol. I really like how the BB times up for me so it is staying in. I get to play on Thursday in a scramble so on a course I play often. I am excited to see how it goes.
I am glad you are having the success you are with it!
I am still loving mine as well. I also hit an X flex version when [USER=15030]@SkiBumGolfer[/USER] came out to visit and it almost didn’t feel like an X because of the flex profile. It was only 1 swing, but me being an S flex person, I didn’t feel that it was too boardy or stiff for me, which is amazing.

It’s the beauty of the whole Diamana line, none of them play boardy. It’s why always gravitate back to the White.
More confirmation this weekend that the BB is such a good shaft for me. @JB even commented at how well it holds up for my swing. I hit some bombs this weekend with this in the DS Adapt X and on some very tight holes. Having a combo that works so well inspires confidence.

Yep, 100%. I said it a bunch in this thread, it’s the smoothest X flex I’ve ever swung. It doesn’t NEED you to go after it to get good results, but it can easily stand up to those aggressive moves.

The BB is permanent in the bag after today’s round!
I haven’t been in here much lately because life has been crazy with the kid and work and family stuff, but I wanted to drop in here again and sing the praises of the BB again. I’ve been having major swing troubles the last month or two, but this shaft is keeping me in it. The last 10 rounds I’ve averaged 270 P-Avg off the tee with driver and still managed to stay in line with my historical fairways hit of about 40%. There’s definitely more in it once I get the swing sorted, but to be able to put out numbers like this with a swing I feel absolutely no comfort with right now is a minor miracle that I attribute to the good fit of both the BB and the GT3.
Oh and the feel continues to stand out. I plugged my old driver shaft back in for comparison once to see if I noticed a difference, and it was immediate. The smoothness of the Diamana line is palpable even in just one swing.
