About this blade

Butterfly Innerforce Layer ZLF is a 7-ply blade built around ZLF fibre placed inner, with Limba on the playing surface and a Ayous core. Its TTDNA profile reads balanced — speed 69, control 58, feel 52 — with a medium response and medium dwell. Physically it measures 5.3 mm thick, around 86 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. ZLF: Pure zylon fibre — light reinforcement that keeps flex and feel while widening the sweet spot.

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.
