Mitsubishi Rayon’s new Diamana BF-Series shafts

Published

Sep 14, 2016

In 2005, Mitsubishi Rayon Composites introduced a mid-launching shaft that became one of the most popular shafts in history. Officially it was known as the Diamana S-Series, but golfers around the world came to know it as the “Blue Board.”

Diamana classics kept coming from MRC — the company later popularized a D-Series, or “White Board” shaft that offered a lower trajectory, as well as an M-Series, or “Red Board” shaft that offered a higher trajectory. Eleven years and many generations later, however, the Blue Board, with its mid trajectory and smooth bend profile, continues to be the company’s most popular model.

This fall, Mitsubishi Rayon has launched the fourth generation of its most premium Diamana Blue Board profile, which it’s calling the BF-Series. The new shaft is designed to replace the company’s third-generation (B-Series) Diamana Blue Board shafts.

Like the B-Series shafts, the new BF-Series shafts use Dialead Pitch Fiber in the butt section of the shaft, which is stronger than carbon fiber. It’s said to provide stability during the loading and unloading process in the transition of the swing, improving energy transfer.

For stability and strength in its tip section, MRC has introduced a new hybrid prepreg that’s never been used before. The hybrid includes boron and a new material called MR-70, which was first introduced in Mitsubishi Chemical’s aerospace sector. Boron adds strength to the prepreg, and the MR-70 material is 20 percent stronger and 10 percent higher modulus than standard carbon fibers, according to MRC.

For a laymen’s visual of what a prepreg is, think of a Fruit Roll-Up (click here for a reminder). Except instead of candy, the flat material is made of carbon fiber, boron, MR-70 and resin. That material is then rolled in specific directions around a mandrel, and baked in a really hot oven to fuse it all together.

The combination of strategically placed materials is designed to make the shaft profile smoother throughout the swing. The result? A slightly lower launch than the B-Series, with more stability, and — if it’s a fit for your swing — a tighter dispersion and more distance.

Slab city on the Korn Ferry Tour — Lead Tape Report

This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.

Joel Thelen

Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.

First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.

Mitchell Meissner

Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

In our forums, one user has offered up a prompt for the true sickos, inviting fellow forum members to share every set of irons they’ve ever owned. As to be expected, this is a lengthy forum topic.

@Lamosteve began:

Can you name every set of irons you’ve owned? Here’s mine

Spalding Dots
Spalding Eclipse
Ram Lazer FX
Lynx Parallax
Mizuno EZ Comp
Ben Hogans
Cleveland CG Red
Taylor Made R9s
PING i20
PING iE1
Taylor Made M6

Our members in the forum have been offering up their own collections. Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”
JimmyC59: “MacGregor Jack Nicklaus Triple Crown. Palmer The Standard. Still play these.”
