Have you ever used bimetal of acanthus?

My best yoyo for contest is Acanthus in TP
Actually it is best for 5A,
I love to use this yoyo in 1A because of

  1. specs
    (small diameter, wide width and heavy weight)
    (I have small hand and I prefer heavy weight)
  2. Nice stability
  3. Powerful spin

Recently, I heard that
in recent Mavetrick Mystery Box,
Prototype of Inner Rim Bimetal Acanthus had appeared
(Just guess, but it seems quite similar to Acanthus)

But I have no information about this
(weight etc.)

Does anyone have this?
If yes, any dramatic differences between Acanthus and this?
