The "Project X" series, trusted by top professionals worldwide, introduces a new model, "Project X Red," for players seeking higher launch angles and moderate spin. This series, favored by major champions including Rory McIlroy, now includes a shaft designed to enhance launch angle and greenside stopping power.
The main feature of Project X Red is its increased flexibility at the tip section. This allows for higher launch and more spin compared to the traditional low-spin, low-launch Project X, significantly improving greenside stopping power.
Meanwhile, the butt and mid sections maintain the same rigidity as previous models, preserving stability and workability. Its strong resistance to wind and high swing repeatability make it suitable for golfers of all skill levels.
Project X Red is truly an "ideal evolution" for players who prioritize launch height and control over just distance. It is currently the most talked-about steel shaft for golfers struggling with shaft selection.
"Iron combo sets" simply refer to a setup that combines different iron models within a single set.
While it used to be common to "match the same model from 5-iron to PW," in recent years, among tour pros, a differentiation has become mainstream:
"Easier to hit long to mid-irons, and short irons focused on workability."
1. Why are "combo sets" becoming popular?
There are two main reasons:
They are "the evolution of ball performance" and "changes in green conditions."
Increased difficulty of long irons
Modern golf balls have evolved to suppress spin to enhance distance performance.
As a result, with traditional muscle-back (01 series) long irons, even professional swing speeds struggle to get the ball up, and there's an increasing number of cases where insufficient spin makes it difficult to stop the ball on the green.
Role change from "distance" to "stopping"
For professionals, long irons (4-5 iron) are not just for gaining distance.
They are clubs for aiming at the pin with a high trajectory and stopping the ball firmly on the green.
Therefore, for long to mid-irons,
there is an increasing trend to combine forgiving models with thicker soles or hollow structures.
2. If you're building a PRGR combo, what's recommended?
PRGR's 01-02 series has a lineup that is very easy to combine for combo settings.
Classic Athlete Combo: 01 × 02
・4-6 iron: 02 IRON (high trajectory and easy to hit for distance)
・7 iron-PW: 01 IRON (prioritizes workability and feel)
Key points
Since the 7-iron of the 01 series (32° loft) will be combined with the 6-iron of the 02 series (28°),
the loft progression is natural, and a combo setting with minimal difference in feel and no discomfort is possible.
