Hurricane 3 vs Hurricane 8 for BH

[Tiz]

Jeon Ji-hee uses H8 on her BH, she actually says that the sponge is Japanese-like so I wonder if she's talking about H8-80.

I had H8-80 37 on a ZJK szlc and it did feel dead after about a month.

So I read somewhere, that WCQ and Sun/Chen both H8-20, which is the orange H3 sponge with the H8 surface.
However, I can't find the article anymore.

WCQ currently uses H3 H38

How is the H8 topsheet different from the H3 topsheet?
