7 plies · Limba surface · ZLC inner fibre · Ayous core · 5.7 mm total
One blade, drawn as technical linework at real shakehand proportions. The laminated edge along the crown and right rim exposes every ply boundary in the stack. Edge depth is illustrative because physical veneer thickness is not published.

Stack order — face A to face B
- 01LimbaOuter ply
Soft, open-grained outer veneer — long dwell, a wooden feel and easy spin on slow strokes.
- 02AyousMedial ply
Very light medial or core wood — keeps the blade low in weight and widens the sweet spot.
- 03ZLCFibre layer
Zylon-carbon — high speed with a softer, more elastic response than pure carbon.
- 04Ayous — coreCore
Very light medial or core wood — keeps the blade low in weight and widens the sweet spot.

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.
