Unified load position design in which all clubs are arranged to the neck and face sides
The unified load position design with higher usability and powerful trajectories is adopted. Every loft ensures the same trajectories and feeling.

Tungsten weight screws are arranged in optimum positions
The tungsten weight screws allow us to design the center of gravity that provides high trajectories and straight-line stability.

The shape is designed to assign top priority to making a shot dead to the pin
The heel share is rounded (following U-03) so that your club has better turf interaction no matter the lie.

The leading edge shape is easy to aim at the target (linear).

ARMRQ ∞ shaft that satisfies the high trajectories, low spin, and easily catches the ball
Even the longer length achieves swings easier than ever before.

Enables the maximum carry distance of the target.
