Blade construction
5W+2 ALC · Inner
7 plies · Limba surface · ALC inner fibre · Ayous core · 5.5 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.

Limba
Outer ply · layers 1 and 7
Softer touch · Longer dwell
Spruce
Medial ply · layers 2 and 6
Fast energy return · Clear feedback
ALC
Fibre layer · layers 3 and 5
More stability · Larger sweet spot
Ayous
Core · layer 4
Lower weight · Wider sweet spot
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.
- 02SpruceMedial ply
Stiff, resonant core wood — fast energy return with a clear, high-pitched feedback.
- 03ALCFibre layer
Arylate-carbon — stiffens the stack and enlarges the sweet spot while keeping a wooden feel.
- 04Ayous — coreCore
Very light medial or core wood — keeps the blade low in weight and widens the sweet spot.
- 05ALCFibre layer
Arylate-carbon — stiffens the stack and enlarges the sweet spot while keeping a wooden feel.
- 06SpruceMedial ply
Stiff, resonant core wood — fast energy return with a clear, high-pitched feedback.
- 07LimbaOuter ply
Soft, open-grained outer veneer — long dwell, a wooden feel and easy spin on slow strokes.

About this blade
Butterfly Innerforce Layer ALC.S is a 7-ply blade built around ALC fibre placed inner, with Limba on the playing surface and a Ayous core. Its TTDNA profile reads fast — speed 73, control 55, feel 46 — with a medium response and medium dwell. Physically it measures 5.5 mm thick, around 88 g, 157 × 150 mm head, FL, AN, ST, CS handles. Butterfly positions it for off- play. Limba: Soft, open-grained outer veneer — long dwell, a wooden feel and easy spin on slow strokes. Ayous: Very light medial or core wood — keeps the blade low in weight and widens the sweet spot. ALC: Arylate-carbon — stiffens the stack and enlarges the sweet spot while keeping a wooden feel.

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.
