I’m the head golf instructor at Tell Me More Golf, and in this article, I will go over the differences and similarities between two of True Temper Golf’s most popular shafts: the Project X 6.5s and the Dynamic Gold X100s. 

Project X 6.5 vs X100 Dynamic Gold Shafts Comparison

The Project X 6.5 and Dynamic Gold X100 shafts have many similarities, but two slight differences immediately stand out.

Target Golfer Compared 

Both of these shafts are made for high-level golfers with fast swing speeds seeking maximum distance and control. However, the Project X 6.5s are made for golfers with a faster and more aggressive tempo. In other words, if you have a very fast backswing and swing speed, the Project X 6.5s might be the better choice. 

Manufacturer Compared  

The Project X 6.5s and Dynamic Gold X100s are from True Temper Golf. However, the X 6.5s are made by Project X, which is a True Temper subsidiary. This means that there can be small differences in the manufacturing process.

Project X 6.5 Pros and Cons

Now, we’ll cover the pros and cons of the Project X 6.5’s shaft weight, swing speed, and flex. 

Project X 6.5’s Shaft Weight

The Project X 6.5 weighs 125 grams, which is definitely on the higher side of the spectrum. Usually, a higher weight means that the shaft is good for fast swing speeds seeking more control. 

This shaft is slightly lighter than the X100, but the difference is relatively negligible and comes down to personal preference. 

Project X 6.5’s Swing Speed

The 6.5 shaft from the Project X line-up is extra stiff, meaning that it’s made for extremely fast swing speeds. It’s difficult to say what swing speed you should have to use this shaft, as there are other factors involved. However, when simplified, you should probably swing a mid-iron over 90 mph.

Project X 6.5’s Flex

The Project X shaft line-up has different shaft flexes, and the 6.5 version is extra stiff. It also has a design that’s meant to withstand a fast and quick motion, which is why it suits golfers with a fast and aggressive swing tempo. 

The X100 shafts are also extra stiff, but they work better for regular swing tempos. 

Dynamic Gold X100 Pros and Cons

Here, we’ll go over the pros and cons of the Dynamic Gold X100 shaft.

Dynamic Gold X100’s Shaft Weight

The Dynamic Gold X100 is also a very heavy shaft, coming in at 130 grams. Golf shafts rarely get heavier than this, and a shaft this heavy is made for golfers with very fast swing speeds. Regular golfers would probably struggle hitting a single good shot with this shaft. 

Dynamic Gold X100’s Swing Speed

It’s hard to say exactly what swing speed an iron shaft is for, as the golfer’s swing also makes an impact. However, it’s safe to say that the X100’s is for the absolutely fastest golfers out there, such as the ones on tour. When simplified, you should probably swing a mid-iron over 90 mph before considering this shaft. 

Dynamic Gold X100’s Flex

The X100s from True Temper’s Dynamic Gold series are extra stiff, which is why only fast golfers should use them. 

Compared to the also x-stiff Project X 6.5s, the tempo the X100s are made for is slightly different. According to True Temper, the X100s suit a moderate tempo, which is calm considering the fast swing speed they’re made for. 

TellMeMoreGolf.com – Frequently Asked Questions

What are the swing speed specs for X100 shafts?

The X100 shafts from True Temper are definitely made for golfers with very fast swing speeds, as they’re extra stiff and very heavy.

Generally speaking, a suitable swing speed for these shafts is tour-level, which is over 90 mph when hitting a mid-iron.

However, they’re not the stiffest shafts out there, and they’re actually made for golfers with a relatively calm swing tempo. 

Is X100 stiffer than Project X 6.5?

Both the X100s and the 6.5 Project X shafts are extra stiff shafts. As they’re also from the same company, they will be very similar in flex.

Instead, what differs about them is their target golfer. They’re both made for high-level golfers, but the X100s suit a slower tempo compared to the 6.5s. 

Is X100 stiffer than S400?

Yes, the X100 shafts from True Temper are stiffer than the S400 shafts. The S400s are only stiff, while the X100s are extra stiff. 

This means that the X100 shafts are only for golfers with extremely high swing speeds, such as tour players.  

What is the difference between Project X shafts and the X100?

There are many Project X shafts available at different flexes, meaning that they can suit a wide range of golfers.

The X100s, on the other hand, are only made for high-level golfers with very fast swing speeds. This is why they’re very popular on tour. 

According to True Temper’s site, the Project X extra stiffs which we’ve covered in this article are made for golfers with a fast and aggressive swing tempo, while the X100s work better for slower tempos. 

Conclusion: 

In this shafts review article, we’ve compared two of True Temper Golf’s most popular shafts, the Project X 6.5s and the Dynamic Gold X100s. Both of these shafts are for high-level golfers with very fast swing speeds, but the main difference is that the X100s are better for a slower tempo, and vice versa.
