Ping G730 Vs Mizuno JPX 923 Hot Metal Irons Comparison Overview

G730 Vs JPX 923

Two irons that are designed to the cater for the higher handicap golfer, albeit to varying degrees.

The G730 are super game improvement, focussed exclusively on distance and forgiveness without much room for workability.

The JPX 923 Hit Metal irons are game improvement irons that cater to high and mid-handicap golfers. Still easy to hit but more workable, shorter and with higher spin rates equating to stopping power on the greens.

Ping G730 Irons Overview

“The G730’s are an upgrade on the G710’s and they have removed the black paint and we can see instead the regalar steel colour”.

The irons are thick and chunky with wide soles and a thick top line to inspire confidence at address.

Expect a low ball flight due to the strong lofts but also a ton of distance.

Since the descent angle is quite low, dont expect to be able to stop the ball on the green too easily.

These irons are for eternal high handicapper who want to hit the ball in the direction of the green consistently without the need to attack the pins and score a number of birdies on each round.

Mizuno JPX 923 Hot Metal Irons Overview

Mizuno JPX 923 Hot Metals

“The JPX 923 Hot Metal irons are game improvement irons made for a super strong Chomoly Steel that produce excellent distance.”

There is also a forged face which produce a pleasing sound and feel that also lets you know when you didn’t catch the ball flush on the face.

The lofts are weaker than the G730’s and the spin rates are considerably higher.

That means less distance, a higher ball flight, more stopping power on the greens and more accuracy.

Overall a quality set of irons for aspiring high handicappers and mid handicap golfers.

Overall the G730’s wil give you more confidence, forgivness and will allow weaker players to hit the ball straight consistently. The spin rates are low and it can be difficult to hold the greens.

The JPX 923 irons will offer more accuracy and allow you to hunt the pins more as a high to mid handicappers while maintaining a lot of the forgiveness seen in game improvement irons.

Mizuno JPX 923 Hot Metal Irons First Impressions

Straight out of the gate the JpX 923 look great, they are not big and chunky like some game improvement irons, but they are not the most forgiving irons on the market either. One thing is for sure, the 923 Hot Metal irons are built for distance.

The irons come in 3 flavors:

JPX 923 Hot Metal High Launch for slower swing speeds to get the ball in the air.

JPX 923 Hot Metal Perfect for Mid Handicappers looking for distance, forgiveness and stability.

JPX 923 Hot Metal Pro – Aimed at consistent iron strikers with more precision, control and workability. Likely to compete with the forged version and the

The next thing that stands out is the V-Chassis on the back which completes the excellent looks of the irons.

It also adds stability to the club face, improves the feel and dampens vibrations on any mishits.

These clubs are faster thanks to the new Nikol Chromoly material that the cup face, and cavity back designed clubs are made with.

It is 35% stronger which a stronger impact and more distance. It also allows the club face to be 8% thinner meaning a better energy transfer. The thinnest point of the face is now also 18% larger and the bigger sweet spot results in better shots on the off-center strikes.

More bounce and stronger lofts also add to the effect of more distance and a higher loft. The extra bounce helps to generate a higher ball flight.

While not being the most forgiving of game improvement irons, they look excellent at the address and offer a ton of distance for players with moderate to average swing speeds and beyond.

The Hot Metal irons are not going to be the best option for beginners and inconsistent strikers but they will be excellent for anybody looking for maximum distance and excellent control, especially in the shorter irons.

Ping G730 First Impressions

“The Irons are long, forgiving and well, quite loud at impact too.”

We see all the hallmarks of the Ping Irons with the deep cavity back, the tungsten weight in the toe and the matching weight in the hosel. We also have the patented Hing towards the heel of the club to add flex to the face.

The Irons look similar to the G430’s except they are bigger and look a little bit more clean cut towards the bottom.

The Pru Flex cavity badge is also present to give a smoother look and feel to the clubs.

When hitting the clubs, they are confidence inspiring. It felt just like hitting a hybrid, in fact, the face was even a little bigger and more inviting.

The problem we encountered was the lower spin rates and the ball running off the back of the green at times.

Who Are the Ping G730 Irons for?

There is no doubt that these irons are catered towards high handicappers, senior players(Correct Shaft) and those who are new to the game.

You are not going to draw the ball around too many Dog Legs with the G730’s but they are great and keeping the ball moving long and straight.

You get what you see with the G730’s, they play how they look, long and straight.

There is no doubt that these are excellent clubs but consider a second hand set if you are new to the game or are a high handicpper for life. There are cheaper options offering similar performance.

Always get your shaft game on point as well.
