Viscaria

The arylate-carbon sits in the outer layers. Carbon near the surface shortens dwell time and increases how hard the ball comes off the face. Put next to Innerforce Layer ALC — the same fibre placed inside — the difference is clear: the official reaction figure is a full grade higher. What the inner version gives back is room to brush the ball.

What is striking is that Timo Boll ALC and Fan Zhendong ALC share exactly the same official reaction and vibration figures. What separates the three is thickness and weight, not numbers. Viscaria is the thinnest of them, so the response at the fingertips is a little more direct. Which one suits you is not settled by a spec sheet; you have to hold them.

It ranks 11th of 45 Butterfly blades for reaction — high, but not at the top. Faster blades like Sardius or Fan Zhendong Super ZLC will send the ball long if your swing does not back them up. Viscaria has lasted precisely because it is not the fastest. It suits intermediate players and up who rally with both wings and need one decisive ball, and is too much for a beginner still building a stroke.

For rubbers, something that grips the ball balances it better than adding more speed.
