As you can see in the composition chart above, the Rotella has an Innerfiber structure, with Limba as the outer ply and an Ayous layer placed directly underneath.
The gluing process involves patented technology, so I cannot go into detail here.
The basic composition is similar to the well-known DHS W968,
but Nexy’s patented technology reinforces the structure by adding more strength through the gluing process.
The Eiger, on the other hand, features Kiso Hinoki as the outer ply,
with ALC positioned right beneath it.
This makes it fundamentally an Outerfiber structure.
However, between the central Kiri core, an additional Ayous layer is inserted,
giving the feeling that the core itself is made of three layers of wood.
From my personal experience, it would be very difficult to make a racket of this quality simply by copying the structure without Nexy’s gluing technology.
It seems unlikely that the two rackets can be compared directly in terms of composition.
A racket with a thick 1mm Hinoki outer ply in an Outerfiber design, versus a racket with a Limba outer ply and an Ayous layer immediately beneath, represent completely different constructions, resulting in distinct feel and performance.
I saw recently Nexy released a blade in China named Wu Ji III (无极 III). Does it also use the double layers gluing technology?
