There's no need for a specific plane to BNZ in... You can BNZ in a Pony as well as a Jug as well as a 109 as well as a P38 as well as a N1K2, as well as a etc... etc....
When you're diving on things you don't really need a high top speed, because the dive gives you speed. With few exceptions (parts shedding on the Ki84, controls locking up in a a6m2) most planes can be used in this role.
If you're only interested in practicing the moves, just use a plane you already like. Why go looking for a new one?
I'm a big proponent of flying all the craft in the game now and then, but do it for the fun of it, not because you want to only fly a certain way.
