UST Mamiya's ATTAS 10 iron shaft is a high-performance iron shaft utilizing innovative technology. This shaft uses a carbon sheet with powdered high-density metal (tungsten) arranged within it, and its optimized weight distribution straightly transfers power to the clubhead, generating incredible distance.
Furthermore, its overall flexible design enhances ease of swinging and control, improving the golfer's feel for their swing. While conventional iron shafts typically become stiffer with shorter club numbers, the ATTAS 10 intentionally controls this difference, designing all club numbers to offer the same feel during the swing. This makes it possible to suppress inconsistencies where short irons perform well but long and mid-irons don't fly as expected.
The vibration frequency is also set linearly, designed so that each club number has the optimal vibration frequency when assembled into an iron. This minimizes variations due to assembly and differences between club numbers, always allowing for swings at the same timing.
Additionally, each model includes a dedicated #11 for wedges such as AW and SW, allowing for accurate approach shots with the same feel as other clubs. Finally, the cosmetics feature a luxurious ion plating finish, a design that enhances the motivation of athletic golfers to aim for the green. While re-shafting incurs an additional labor cost, you are sure to experience its performance and beauty.
<PRGR Iron Strongest Combo>
A "combo set of irons" is, simply put, a setup that combines different iron models within a single set.
In the past, it was common to have "the same model from 5-iron to PW," but in recent years, it has become mainstream even among tour professionals to differentiate between clubs, where
"long to mid-irons are easy to hit, and short irons prioritize operability."
1. Why is the "combo set" popular?
There are two main reasons.
These 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 flight distance performance.
Therefore, with conventional muscle-back (01 series) long irons, even professional head speeds struggle to get the ball airborne, and there are increasing cases where insufficient spin makes it difficult to stop the ball on the green.
Shift in role from "distance" to "stopping"
For professionals, long irons (4-5 iron) are not just about gaining distance.
They are clubs for aiming at the pin with a high trajectory and stopping the ball firmly on the green.
Thus, for long to mid-irons,
there is an increasing trend to combine highly forgiving models that feature thicker soles and hollow structures.
2. If building with PRGR? Recommended Combos
PRGR's 01-02 series is actually a lineup that is very easy to combine into a combo setting.
Classic Athlete Combo: 01 × 02
・4-6 iron: 02 IRON (flies easily with a high trajectory)
・7-iron to PW: 01 IRON (prioritizes operability and feel)
Points
Since the 7-iron of the 01 (loft 32°) is combined with the 6-iron of the 02 (28°),
the loft connection is natural, and a combo setting with minimal difference in feel and no discomfort is possible.
