The UST Mamiya ATTAS 40/50/60/80 iron shaft is a high-performance model that incorporates the latest technology. This shaft effectively places high-density metal (tungsten) in powder form within the carbon sheet. This design ensures optimal weight distribution according to weight class, directly transmitting power to the clubhead and generating distance.
Furthermore, the full-flex design enhances ease of swinging and control, improving the playability golfers seek. In particular, the NEW ATTAS IRON adopts a flex design that varies by club number. While typical iron shafts tend to get stiffer as you move to shorter irons, this model intentionally controls that difference. It is designed so that golfers can swing with the same feel across all club numbers, which helps reduce variations where short irons perform well but long or mid-irons don't achieve distance.
Additionally, by linearly setting the oscillation frequency, the shaft is designed to achieve the optimal oscillation frequency for each club number when assembled into an iron. This minimizes variations due to assembly and differences between club numbers, enabling consistent swing timing. Moreover, each model includes a dedicated #11 for wedges, allowing golfers to swing with the same feel even with wedges, leading to accurate approach shots.
The cosmetic features a luxurious ion plating finish, creating a design that boosts motivation when aiming for the green. While an additional fee is required for reshafting, you are guaranteed to experience its performance and beauty.
＜PRGR Iron Strongest Combo＞
Simply put, an "iron combo set" is a setup that combines different iron models within a single set.
Previously, it was common to "have the same model from 5-iron to PW," but in recent years, even among tour pros,
"Easy-to-hit long to mid-irons, and control-focused short irons"
has become the mainstream approach.
1. Why are "combo sets" so popular?
There are two main reasons:
"Evolution of ball performance" and "Changes in green environments."
Increased difficulty of long irons
Modern golf balls have evolved to suppress spin to enhance distance performance.
As a result, with conventional muscle-back (01 series) long irons, even with a pro's head speed, it has become increasingly difficult to get the ball up and to stop it on the green due to insufficient spin.
Shift in role from "distance" to "stopping"
For pros, long irons (4-5 iron) are not just about gaining distance.
They are clubs for aiming at the pin with a high trajectory and firmly stopping the ball on the green.
Therefore, for long to mid-irons,
There's an increasing trend to combine highly forgiving models that feature thicker soles and hollow structures.
2. What if you're building with PRGR? Recommended combo
PRGR's 01-02 series actually offers a lineup that makes building a combo setup very easy.
Classic Athlete Combo: 01 × 02
・4-6 iron: 02 IRON (high trajectory, easy distance)
・7-iron to PW: 01 IRON (emphasis on control and feel)
Key points
Since the flow is to combine the 02 6-iron (28°) with the 01 7-iron (32°),
The loft progression is natural, and there's little difference in feel, allowing for a comfortable combo setup.
