The Next Line of Hot Metals are Engineered for Custom
By Ryan Gager
The new JPX923 Hot Metal irons are out and available for purchase at your local GOLFTEC. Mizuno says that the JPX923 irons are engineered for custom performance, which we definitely recommend getting custom fit for any golf clubs you use. There are five unique iron models within this line, created from three specific metals, based on Swing DNA data from over 350,000 real golfers. The expanded head options combine with several shaft options for specific trajectory, ball speed and ease of use. This creates options for elite tour players, slow swinging amateurs and every player in between. Mizuno product lead, Chris Voshall explains the JPX923 lineup of irons below. Be sure to talk with your GOLFTEC Coach about trying out the Mizuno JPX923 Hot Metal irons in your next fitting.
Mizuno JPX923 Hot Metal Irons Family
With this filled out line of JPX Hot Metal, we have a golf club that has the proper amount of stopping power for what you and your swing DNA delivers at impact.
We have the High Launch that’s going to go higher and come in steeper with little bit more spin. We have the Hot Metal that’s going to come in a little bit shallower, but still deliver plenty of spin. And then the Hot Metal Pro for if you need a little bit thinner, look at address.
Original Chromoly has been a great material for us – but the new Hot Metal irons all feature our new Nickel Chromoly, that’s 35% stronger than the previous version. In summary that allows us to go thinner again across the entire face. The material is so strong that our first prototypes were far in excess of the limits set by the governing bodies – we had to thicken the faces for them to conform – the first that’s happened to us within an iron development.
Also, we dialled in our V-chassis to make sure the feel is phenomenal. Yes, it’s a hot golf club, but it’s hot and solid at the same time. It’s a Mizuno version of Hot. It still feels solid. All of the Hot Metals are going to help deliver a golf ball that just launches. It’s going to spin. It’s going to have a ton of speed. And then the specs are going to dial in how it fits you.
The Hot Metal is the middle one of this family. It’s the very traditional, slightly oversize head, slightly thicker top line and slightly thicker sole.
The Hot Metal Pro is the player’s version of that – same ball speed, same distance. Thinner top line, thinner sole, less offset.
Hot Metal High Launch is on the other end of that. This is for that player who wants all that speed but needs a little bit more launch and even more stopping power coming in to the green. We see a lot from fitting and from playing with other golfers to recognize certain trends, but to be able to quantify it is a whole other thing. Shaft Optimizer allowed us to quantify the number of players that need that added spin, and we’ve seen it at close to 50%. Our Shaft Optimizer data has shown that when you look at average angles of attack and average shaft lean, players are delivering these distance irons with too little effective loft. As a result of that, we see a lot of players with Irons that are coming in too shallow.
As a result, this extended Hot Metal series means there is likely going to be a route to more ball speed for most players – but with the right stopping power too.
*Note: in the video, Voshall talks about the JPX923 Tour and Forged irons as well. These irons are scheduled to launch in Q1 of 2023.
