The Mitsubishi Diamana ZF shaft is the blend of the “blue” and “white” profiles that Diamana fans have always been waiting for. Superb feel.
In the world of golf shafts, there are very few constants, but the Diamana name is one of them. Over four generations of product, Diamana has become synonymous with quality, smooth feel, and a mountain of Tour usage and wins.
But even the most storied brands need to evolve, so, for the first time, Diamana is adding a fourth profile to the family. The new Diamana ZF Series is already in the bags of Justin Thomas and other PGA Tour players, and I was eager to see why.
If, like me, you’re a fan of Diamana’s beautiful, understated graphics, you’ll love the look of the ZF Series. The ZF has a shiny silver base color that stands out in a world gone matte. Its graphics are identical to the other Fourth Generation Diamana shafts – the signature flower band near the grip and Diamana branding below that. One pleasant surprise was the iridescence of the graphics. It’s subtle (and hard to capture in photographs), but it’s a visual kick when the sun hits it just right.
The Diamana ZF-Series is billed as taking the BF-Series (review HERE), and pushing it “in just the right places.” As you can see in Mitsubishi’s graphic below, that means that the ZF is stiffer in the butt and tip with slightly more action in the mid section. Comparing it the DF-Series (review HERE), the ZF is much stiffer in the butt but softer in the middle and tip.
Testing the ZF-Series shaft in a 60-TX, my first swing reaction was amazement at how smooth and active it felt, even in that TX flex. As you can see in the chart, the stiffness falls off sharply under and near the grip, and I absolutely felt a hinge and an explosion in that area. This is contrasted with a tip section that feels very stable.
Among golfers who play Diamana shafts, blue vs. white has been a longtime debate. The introduction of the ZF-Series may break down those divisions. With a smooth, explosive feel and great tip stability, it has something for every player.
The real world results that I saw matched the feel precisely. My ball speed ticked up slightly, the flight was mid-launch and very strong, and the dispersion was excellent. I was turning the ball over a little more than normal, but there were no hooks, only draws.
While it’s hard to point to one aspect of the Diamana ZF as my favorite, what stands out most is the way it handles all types of swings. Some shafts that are very active encourage you to swing within yourself but get loose if you don’t. Other shafts only activate when you stand on them. The ZF has plenty of kick when you swing smooth, but it can also handle your 110% swing.
The Diamana ZF shaft is available in weights ranging from 40 grams to 80 grams. In the lightest weight, they offer R2, R, and S flexes. At 50 and 60 grams, MCA offers R, S, and TX (there is no standard X in the ZF). The heaviest versions, 70 and 80 grams, are available in S and TX. This is the first fourth-generation Diamana shaft to be offered in the 40 gram weight class.
Whether you’re a long time Diamana fan or a newcomer to the brand, the MCA Diamana ZF-Series shafts are absolutely worth a trip to your local fitter. It blends an active feel with a solid tip and wraps it all in Diamana’s signature smoothness. The Diamana ZF is going to be a serious contender to go in my driver in 2020.
