Project X 6.0 Shaft2

The Project X stepless steel iron shaft is where it all began.

This was the shaft that really vaulted Project X into the limelight and made the company a household name…well, for golfers at least.

But make no mistake about it: the Project X is not for the faint of heart.

After re-testing it for today’s review, my first thought was “yep, it’s just as stout as people say.”

In fact, the original Project X steel shaft has earned a reputation for putting off slower swing speed players.

Today I will be giving you some insight into the Project X 6.0 specifically.

Project X 6.0 Shaft Overview

The Project X 6.0 was designed to have a consistently stiff tip and butt section.

But the midsection stiffness is progressive and tightens up as you move to the short irons. For my swing, this was a perfect fit.

I tend to generate mid spin and launch so the Project X 6.0 made me look like a better player than I actually am.

My short iron shots were more controlled and I was reaching the green on long approaches more often.

The Project X 6.0 has a very simple look: a polished chrome finish with a band in the middle containing all the branding, lettering and specs.

I’ve always preferred the look of stepless shafts too but that’s just a matter of opinion. The kick in this shaft is very subtle.

In fact, I would say that only strong swingers will be able to feel the shaft load and unload.

Still, it maintains a smooth transition whether you are swinging out of your shoes or taking a more controlled shot.

Our testing team had the same reaction. Some adjectives I heard from them included “smooth,” “stable,” and “controlled.”

But the Project X 6.0 is certainly not for everyone. Some of our slower swing speed testers were getting pretty wide dispersion with this shaft, in fact.

They couldn’t jive with the stout feel and when you don’t like the feel of the shaft, it likely won’t be compatible with your swing.

And a shaft that doesn’t groove with your swing is likely to produce poor performance results.

Why is the Project X 6.0 So Popular?

The Project X shaft is considered a classic in 2023.

It is a popular choice among powerful swingers because it affords them the club head control they need to maximize distance and stay on the fairway.

How Does the Project X 6.0 Perform?

The Project X 6.0 performs almost exactly as it’s advertised to. It produces low launch and low spin numbers.

So for a player like me who usually produces a mid launch and mid spin numbers, this shaft brought my launch and spin rates down just a bit. The Project X 6.0 wants to keep you on the fairway.

The only issue I had with this shaft was rollout. The low spin and launch combo doesn’t make for amazing stopping power. However, this may only be an issue for players like me.

If you know how to impart spin on the ball or are naturally a high-spin player, you may get along very well with the Project X 6.0.

Plus, you can always go down a flex if the spin/launch combo is making it hard for you to stick greens. The distance you get out of the Project X 6.0 shaft will depend largely on your swing speed.

I wouldn’t recommend the Project X 6.0 for anyone swinging slower than 85 MPH. If you are a 85+ MPH swinger though, you will likely pick up yardage through tighter dispersion alone – not to mention smash factor and ball speed.

What Flexes Are Available? What Swing Speeds Do They Suit?

The Project X 6.0 specifically is a stiff flex shaft.

There are other flexes available but 6.0 is for players in the 85-100 MPH swing speed range.

Again, the Project X 6.0 specifically is a 120g shaft.

This is a good weight for players who swing their irons between 85 and 100 MPH.

Why is it So Good?

The Project X 6.0 is incredibly stable.

It can keep your strongest swings straight and amazingly, it doesn’t send the ball veering off-line on mis-hits.

Project X 6.0 First Impressions

I was instantly reminded of how stout this shaft feels as soon as I took my first swing.

There is no lag in this shaft. Instead, you can feel the club head keep up with you throughout your swing.

Key Features & Performance

The Project X 6.0 uses a progressive midsection stiffness profile which makes the performance more dynamic. It gives you more speed in the long irons and more control in the scoring irons.

Project X 6.0 Irons Review

Even in the more reactive long irons, you get excellent control and tight dispersion. These shafts are fairway finders for sure.

Project X 6.0 Wedges Review

Better players will certainly be able to achieve acute spin control in the stouter wedges.

Still, launch remains pretty low and hard to work upward.

Who Should Buy it?

The Project X 6.0 should at least be tried by fast swing speed players.

If you are a single-digit golfer seeking maximum control from your irons, the Project X 6.0 should be on your radar.

Even some faster swingers will be put off by the very stout profile; but if you are used to a stiff, traditional-feeling steel iron shaft, this shouldn’t be a problem for you.
