New Mitsubishi Chemical ZF shaft in play at the Tour Championship
Even after winning just a week ago, Justin Thomas has put a new MCA Diamana ZF-Series shaft into play for the Tour Championship and FedEx Cup Final this week at East Lake Golf Club. JT is using the 60g TX version in his 9.5-degree Titleist TS2 driver (see Thomas’ BMW Championship-winning WITB here).
MCA has confirmed the new shaft and given us some great information on why it is are adding this fourth profile to the Diamana line—something the company has never done before.
The new Diamana ZF has taken the easy loading bend profile from the BF-Series and tweaked it in certain spots along the length to further maximize the design and find greater performance for players across swing speed ranges.
“The result is a profile that makes ZF a little more explosive and easier to accelerate.” -Mark Gunther, Vice President of Sales and Marketing for MCA GOLF.
Like the other shafts in the Diamana Fourth Gen. Series, the Diamana ZF shafts owe their stiffness and stability to two unique technologies. First: the MCA-developed MR70 carbon fiber material, and the second: Boron fiber. MR70 is found in both the butt and tip sections of the shaft and is 20 percent stronger than conventional materials, with a 10 percent greater modulus (a measure of stiffness). These designs have additional strength thanks to Boron fiber in the tip section to create the exact EI curve desired.

When you compare the new ZF to Diamana BF-Series, the ZF-Series shafts are a slightly stronger profile and built to have increased stability in both the butt and tip sections. They feature a softer, more active middle for better energy transfer and clubhead acceleration.
A cool feature for those looking to get a bit more distance but are on the lower end of the swing speed spectrum: There will also be a 40-gram version of the ZF, which is the lightest shaft of the fourth generation Diamana family.
“We’re extremely happy to have a 40g option within Diamana™ ZF,” says Gunther. “This opens the performance benefits of these unique Mitsubishi Chemical materials to a whole new range of players who prefer to play an ultra-lightweight shaft.”

Neal Shipley, AKA, the “Big Fridge’s,” custom stamping
Neal Shipley was the first to admit that he enjoyed his food while in college. But since his days at Ohio State, he’s slimmed down and earned a PGA Tour Card.
That hasn’t stopped him from having fun with his wedge stampings, though it’s led to some misunderstandings.
On the 54 (degree), we have ‘Big Fudge,'” Shipley told GolfWRX. “It was supposed to be ‘Big Fridge,’ so this happened a little while ago. ‘Big Fridge’ was a nickname between my college teammates and I, with ‘fridge’ meaning stomach, a big stomach.

“We told the Ping guys to put … ‘Big Fridge’ on it, and I think maybe some bad cell service or something, and they thought I said ‘fudge,’ so they put fudge on it.”
On Shipley’s 50-degree he also continues the food theme, this time with his go-to order at the “Golden Arches,” and his stamping “DONS 7.”
“The number 7 meal, the two cheeseburger meal, that was my McDonald’s order, back when I would have McDonald’s frequently,” Shipley shared.
