Named Innerforce ZLC in European shops. Rubbers for this snapshot are not in the May 2026 extract we used.
Reported equipment, mapped onto this catalogue. Not a lab test and not a sponsored list. Personal national-team woods are labelled when the EU SKU is only a sibling. Combined specs on product pages stay unboosted.

Butterfly prints Franziska Innerforce ZLC as a current named inner-fibre wood. That is the SKU to open if you wanted his spare-part blade, not Viscaria.
Innerforce ZLC is stiffer than Layer ALC. Tenergy / Dignics are the usual Butterfly guesses next to it — guesses stay off the rubber row until a list names them.
