To enhance golf club performance,
the "SteelFiber fc series" stands at the forefront of ever-evolving technology.
This shaft was developed by AEROTECH experts, renowned for their high usage rate on the PGA and LPGA tours in the USA,
and has undergone further evolution as part of True Temper Sports.
Its secret lies in its innovative design, which fuses graphite and steel.
By using graphite in the core and incorporating SteelFiber in the outermost layer,
it achieves both distance performance and stability.
Furthermore,
to achieve the optimal trajectory for each iron,
it is designed to produce a mid-to-high trajectory for long and mid irons,
and a suppressed trajectory for short irons.
The SteelFiber fc series offers a wide range of options to suit a player's individuality and swing.
With weights ranging from 70g to 115g,
players can choose the optimal shaft to match their tempo and swing speed.
This shaft, alongside Dynamic Gold and Project X,
serves as a new option for iron shafts, meeting the expectations of golfers.
An "iron combo set" simply refers to a club setup where different iron models are combined within a single set.
While it was once common to have "the same model from 5-iron to PW," in recent years, among tour pros,
"easy-to-hit long to mid-irons, and highly workable 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 increase 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 for the ball to get airborne and stop on the green due to insufficient spin.
Shift in role from "hitting far" to "stopping"
For pros, long irons (4- to 5-irons) 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.
Therefore, for long to mid-irons,
there's a growing trend towards combining more forgiving models with thicker sole designs or hollow structures.
2. If you're building with PRGR? Recommended Combos
The PRGR 01-02 series is actually a very easy lineup to create a combo setting with.
Classic Athlete Combo: 01 x 02
・4-6 iron: 02 IRON (easy to hit for a high trajectory and distance)
・7-iron to PW: 01 IRON (focus on workability and feel)
Key Point
Since the 7-iron of the 01 (loft 32°) would naturally flow into the 6-iron of the 02 (28°),
the loft progression is natural, and with little difference in feel, a seamless combo setting is possible.
