A One

A One is one canonical Double Fish identity. The listings A-One and A1 are alternative spellings of the same rubber and are never separate records. The name appears in the researched approval inventory, but no current official technical sheet could be confirmed, so hardness, thickness and colour options are left empty rather than estimated.

Approval evidence and market availability are recorded separately. A name listed by an approval source is not proof that the rubber is currently on sale, and a rubber on sale is not proof of a current approval. Approval is never inherited by a suffix or edition, and no expiry date is invented.

Market status describes current commercial availability only. Where it could not be verified it stays unknown rather than being guessed from a shop listing.

Printed hardness values are manufacturer figures on the maker's own scale. A printed Chinese degree is not assumed to equal an ESN degree, and no hardness is inferred from a product code or a sponge colour.

No reliable official Double Fish list price is published per region, so no price is shown rather than an invented one.

Variants and configurations

1 variant

Colour, thickness and configuration are variants of one model — never separate products. Colour never changes a rating, MAX and OX stay qualitative labels, and OX carries no sponge hardness.

Offensive club and league players who want a spin-first inverted sheet on the forehand or backhand.

Double Fish publishes no athlete roster for this sheet, so TTDNA shows the player profile it is built for instead of invented names.
