Stack order — face A to face B
- 01AyousOuter ply
Very light medial or core wood — keeps the blade low in weight and widens the sweet spot.

Paulownia core — extremely light, damping the stack and slowing the blade down for control.

About this blade
Butterfly Outerforce ZLC is a 7-ply blade built around ZLC fibre placed outer, with Ayous on the playing surface and a Kiri core. Ayous in the outer layer: Very light medial or core wood — keeps the blade low in weight and widens the sweet spot. Kiri in the core: Paulownia core — extremely light, damping the stack and slowing the blade down for control. ZLC in the fibre layer: Zylon-carbon — high speed with a softer, more elastic response than pure carbon. Physically it measures 5.9 mm thick, around 85 g. Butterfly positions it for off play.
TTDNA ratings
NormalizedPerformance
Construction
Material properties
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.
TTDNA ratings are normalized comparison values, not laboratory measurements. They are built from published specifications, technical sources and structured product evidence, converted to one 0–100 scale. Where a directly comparable measurement is unavailable, the value is an evidence-based estimate. Overall-style scores are composites of several characteristics. Methodology
