What better way was there to celebrate TWENTY years of Diamana than for Mitsubishi Golf to bring back the White Board? That alone would have been enough to turn heads and perk up ears, but for the 6^th generation version of the Diamana WB they have also brought back the legendary surfboard and flower band graphics. Rest assured though, this is not a rehash as the 6^th Gen features all new materials and technology within that classic look. 

We were able to get the new Diamana WB in 63 S and X for a closer look to see how modern and classic have been melded together. 

Quick Take

Don’t let the throwback looks fool you, while visually this is a nod to the past 20 years, the Diamana WB from Mitsubishi is not the same old Whiteboard. The shaft is rebuilt from the ground up with all the cutting-edge materials and application processes you would expect, and the result is a low-low classified shaft that produces a powerful ball flight with superb dispersion and a feel that is as smooth as anything on the market. 

Mitsubishi Diamana WB – Design

It needs to be made very clear that this is not just a rehash of the old Diamana WB designs, through Mitsubishi wanted to tip the cap to the twenty years of history which the WB has made, this is truly a modern build. 

The biggest thing is the application of 80-ton DIALEAD pitch fiber in the handle which showed a notable jump in energy transfer through the swing based on Mitsubishi’s internal testing. They have also implemented aerospace-grade MR70 carbon fiber the full length of the shaft to increase strength as well as a change in orientation of the 46-ton fiber used in the tip which brings down torque to tighten dispersion. All of that however, is made more effective thanks to the “Xline Tech Resin System” which allowed for more carbon fiber to be used thanks to decreasing the resin needed. 

Mitsubishi Golf has also brought back the classic 43, 53, 63, 73, and 83 weight classification system to add just a bit more nostalgia to it all while also providing fitters with a plethora of options across the board.

Mitsubishi Diamana WB – Performance 

As mentioned earlier, we received the Diamana WB 63 S and X from Mitsubishi to work with in this review. All the testing was done with the shafts both installed into Cobra adapters which were plugged into a 9.0 Darkspeed LS driver head set to standard with the heavy weight forward. 

Aesthetically speaking, these are stunning. It is absolutely fantastic to see Mitsubishi Golf embracing the history for the 20^th anniversary of Diamana, but in our opinion, this should be the permanent look for the WB. As much of a classic as it is, it also looks good in any driver head on the market while being one of the most easily recognizable driver shafts on the planet. 

As for performance, launch monitor and on course testing showed the Diamana WB was everything expected, living up to the high kick-point and low/low classification. Off the 9.0 head, the ball flight was penetrating, and more importantly, the down range dispersion stood out while working with both setups. As the data below will show you, the two shafts separated themselves exactly as anticipated based on the flex change with the 63 S spinning just over 200 RPM more while producing a slightly higher launch angle and thus, higher peak. 

A big stand out of both shafts through many shots hit over several weeks was the consistency, not just in those basic ball flight characteristics, but how point and shoot they both played for me. Sure, there could be some fine tuning done in the setup to maximize things a bit more on a personal level, but by putting them both in the same exact setup, you can clearly see the similarities and differences. Worth mentioning as well, both flexes allowed for working the ball both left and right equally depending on the shot that was needed. 

Honestly, they do exactly what I anticipated any iteration of the Diamana WB to do, except one thing. Having hit many of the previous versions, none of them have ever captured feel and flow like the 6^th generation. There is no “boardy” to the White Board, instead there is a fluidity which can only be described as bringing smoothness into a powerful shaft design which wants to produce rockets off the clubface. Clearly, the WB won’t be for everyone, but for those who tend to fit into a higher kick point design, it shouldn’t be slept on as just a revamp, this is both a familiar and entirely different animal than we have seen before from the Diamana lineup. 

The Details

Availability for the 6^th Generation Diamana White Board from Mitsubishi Golf is worldwide now through fitting centers and custom orders across the globe. By offering weights from 43g all the way up to 84g, the new WB lives up to the fitting potential which put its predecessors on the map. Price point for the shafts are set at $400.00.
