Mitsubishi Diamana WB: Club Junkie takes a technology deep dive
Earlier this week, Mitsubishi announced the return of its iconic Whiteboard profile with the new Diamana WB shaft.
In our launch story, we offered a rundown of the key technology in the new WB — 80-ton Dialead pitch fiber, Aerospace-grade MR70 carbon fiber, Consistent Feel Design, and the Xlink Tech Resin System. To go deeper, however, we enlisted our Resident Club Junkie and bona fide shaft nut, Brian Knudson, to track down someone from Mitsubishi at the PGA Show. Fortunately, Mitsubishi’s Director of Global Aftermarket Sales, Jonathan Alongi, was on hand to answer all of BK’s questions.
Check out their discussion about the new WB, as well as the 20th anniversary of the original design, in the video above — time stamps of key points below, including a definitive answer as to how the surfboard graphic ended up on the original Whiteboard in 2004!
- :40 – Mitsubishi Japan expands to the U.S. in 2004
- :50 – “The shaft that set the standard”
- 1:12 – “The ‘board is back”
- 1:45 – WB or Whiteboard? Or both?
- 1:55 – The first iteration of the sixth generation of Diamana
- 2:10 – Incorporating key technology from a 20-year journey
- 3:10 – Modifying the tip section for more ball speed
- 3:50 – Delivering ball speed in a low-launch, low-spin shaft
- 4:20 – Drilling down on the shaft profile compared to the original Whiteboard
- 5:00 – The most impressive element of the new WB
- 5:30 – Butt, mid, tip specifications
- 6:00 – WB’s iconic graphics and the Diamana legacy — flowers, surfboard, numbering system
- 8:15 – An abundance of available weights and flexes
- 8:55 – More players going lightweight

Three Swing Challenge: Testing the Edel Array F-2 putter
![](https://www.golfwrx.com/wp-content/uploads/2024/07/3SC-YT-Thumbnail-Template-Edel-Putter.png)
This week on the Three Swing Challenge, we have the Edel Array F-2 putter. With the Array line of putters, Edel gives golfers several different options to match their putting styles and tendencies. It is a cool concept, but let’s see how it performs.
Why three swings?
Many years ago, the legendary Barney Adams, founder of Adams Golf told us this:
“My formula as a fitter was three shots only. I discounted No. 1 just because it was the first one, counted 100 percent of No. 2 and discounted No. 3 because the player was starting to adjust.”
