Apparently video posted at the CJBDY forum showing a J-20 in yellow primer caught on film in Chengdu displaying super-manoeuvrability, including Pugachev's Cobra. 😯

Has anyone seen it before it was deleted? 🤔

Do you mean this one? "J-20 does cobra maneuver over snowy mountain, warns India (china-arms.com)"
"https://www.china-arms.com/2021/07/j20-cobra-maneuver-snowy-mountain/"
(This site china-arms is weird. It was inactive from 2016 to 2020. It's definitely not run by PLA but could it be by US DIA?)

An all moving vertical stabilizer would definitely make it more manoeuvrable. This also means the vertical stabs can be kept smaller.

Downside is that you need ventral strakes to provide stability at high AOA.
Those ventral strakes were reportedly known as made of electromagnetic wave absorbent material. Worth noting it is wave absorbent material but wave transparent or wave through material, which means EM wave will not get through and hit the fuselage. Instead its energy will be partially absorbed by the ventral strakes while remaining energy will be deflected to other directions.
