YY top-level lenses (price 1680 yuan and 1720 yuan) are YY top-level, and there is no difference between good and bad, only whether they are suitable for different users.

But since you are asking about the flagship, I think it contains the meaning of "the latest flagship", which is obviously the ARC-Z (Arc Saber Z-Slash-Bow Z) launched last autumn. Pricing is also 1720, with innovative design. YY has made great efforts to promote this kind of racket.

The limited edition of AT700 mentioned upstairs is mainly in the special sense of limited edition, and the beat itself is no different from the new color of AT700, which means it is not the flagship in performance.
