Stack order — face A to face B
- 01KotoOuter ply
Hard, dense outer veneer — a crisp, direct hit and plenty of speed straight off the bounce.
- 02CNFFibre layer
Cellulose nanofibre — a soft, damping reinforcement with a very wooden, quiet impact.
- 03AyousMedial ply
Very light medial or core wood — keeps the blade low in weight and widens the sweet spot.
- 04Kiri — coreCore
Paulownia core — extremely light, damping the stack and slowing the blade down for control.

Playing profile
A TTDNA blade rating measures how much of the named characteristic a blade has. For descriptive rows — flex, stiffness, vibration, head heaviness, weight, thickness, carbon feel, softness, technique requirement, spin sensitivity — a higher number means more, not better.
