This is due to differences in the way the stick axis structure (mechanism) is thought of.
For the configuration we call "AXIS" at MERKA.G, the axis (stick box) itself is made by ALPS.
We also tested the Ginful stick box (axis mechanism), and determined that there were large individual differences in the feeling of returning to the center (the timing of the return and the texture of the rebound).
This is not due to the superiority or inferiority of performance, but rather to the fact that the standards for operational feel change significantly.
For this reason, MERKA.G uses an ALPS shaft structure that is familiar to many users and easy to align with standards.
