Customization has become all the rage when it comes to drivers in recent years, and there might not be a driver on the market today that offers more customization than the Mizuno JPX 900.
Two eight-gram weights can be moved into different positions along the Infinite Fast Track that runs perpendicular to the clubface to help players achieve exactly what they’re looking for in terms of launch angle and spin rate. Moveable weight tracks are also positioned at the heel and toe, which gives golfers the ability to manipulate ball flight by creating a draw or fade bias.
Additionally, an adjustable hosel allows for +/- 2 degrees of loft adjustment to influence launch, while an adjustable sole plate creates the ability to alter face angle to give any player their preferred look (open, closed, or neutral) at address.
This is a driver, however, that offers much more than just extensive personalization options.
From a technology standpoint, the lightweight CORTECH clubface is thinner and creates faster ball speeds from impact points across the face, and the weight saved in its design has been moved to enhance MOI.
Also of note, an innovation that Mizuno calls Harmonic Impact Technology has been utilized to deliver amazing feel and acoustics at impact, which was not lost on TGW customers during consumer testing.
“My current driver tends to be a little noisy at times and (with) this the sound is great. Very muted,” said Jay, a +4 handicap. “But the way it feels coming off (the face) is still very impressive.”
The JPX 900 driver also has a classic, compact head design that was inspired by tour players and comes with an eye-catching matte blue finish.
The stock shaft for the JPX 900 driver is the aftermarket, “real-deal” Fujikura Speeder EVO II 569, which is a mid-launch and mid-spin shaft from a profile standpoint. Other custom options are also available at no upcharge.
As mentioned, Mizuno has been best known for its classic looking, great feeling players irons, and the JPX 900 Tour falls directly into that category.
Forged construction, thin toplines, compact blade shapes, and minimal offset all provide evidence that this is an iron intended for a quality ball-striker, which is true, as these irons will deliver maximum control and workability along with exceptional feel.
JPX 900 Tour irons also feature the thinnest soles ever utilized in a JPX iron, allowing players to shape shots easily, and rounded leading and trailing edges help provide better turf interaction.
Also, in addition to being forged from 1025E Carbon Steel, a specialized heat treatment utilized in the construction process creates an ideal combination of softness and strength, which leads to superior feel and acoustics at impact.
All that said, this is an iron that’s more forgiving than one might expect thanks to its Power Frame design, which moves mass to the perimeter of the clubhead to maximize stability at impact and keep ball speeds high on mis-hits.
While this is an iron that was built to meet the needs of the best players in the world, there’s enough forgiveness incorporated into the design that higher single-digit handicappers, especially those who find the center of the clubface more often than not, could play this club with success.
The stock shaft for the JPX 900 Tour irons is the True Temper Dynamic Gold S300 shaft (stiff flex).
Tying the label the JPX 900 Forged irons into a particular category isn’t an easy task.
After all, these irons have a clean, compact look and have been forged for exceptional feel, but they’re also incredibly forgiving and deliver impressive distance and naturally high launch conditions.
That’s one reason why this is an iron that could be an excellent fit for low-, mid-, and even high-handicappers depending on their individual preferences and needs.
Leading the way in terms of the dramatic distance the JPX 900 Forged irons generate is the utilization of Boron in the design, a material that’s significantly lighter and stronger than Carbon Steel.
The Boron enables a thin, hot clubface for faster ball speeds and allows weight to be redistributed to the perimeter of a reshaped Pocket Cavity to optimize forgiveness and maintain high ball speeds from impact points across the face.
While the JPX 900 Forged irons offer some of the performance attributes of better game-improvement irons, their look, feel, and workability are vintage Mizuno, which will certainly appeal to better players.
The stock shaft for the JPX 900 Forged irons is the Project X LZ 5.0 steel.
While the JPX 900 Forged irons would be hard to categorize, the JPX 900 Hot Metal irons easily fall into the game-improvement category. And where they really excel is in terms of producing explosive distance.
A new material called Chromoly 4140M being used by Mizuno in the Hot Metal design is 15 percent stronger than 17-4 Stainless Steel, which enables an ultra-thin clubface that produces exceptional ball speeds.
Also contributing to the distance that the Hot Metal irons generate is a Unitized Face Cup that allows for a lower CG placement, which also helps create more forgiveness on mis-hits and improved stability at impact.
The Power Frame, meanwhile, moves mass to the perimeter of the clubhead to maximize MOI and by being more rigid provides a softer feel and sound at impact than one might expect from a cast club.
As mentioned, JPX 900 Hot Metal irons are clearly a game-improvement offering, but compared to many other irons in their category they have smaller overall blade sizes, thinner toplines, and less offset.
For that reason, while this iron is an ideal fit for mid- and high-handicappers, it might also appeal to some better players, especially those who are searching for more distance without having to completely sacrifice feel and aesthetics.
The stock shaft for the Hot Metal irons is the Project X LZ 4.5 graphite.
