Kats, I do not recommend you the tail slide move. Usually, you'll end up with your tail closer to the enemy guns. With tail slide you give the con more time to close to you and to aim and spray to your tail. With hammer you are goin to reverse quickly and to put your guns on enemy instead your tail.
Most of the times, tail slide will end up with a short flat spin, giving the con even more chances to disintegrate your plane.
Extreme, never tried hammer with P51, but with G10 the method is the same than 190 (a bit slower). I suppose that same moves will end up with hammer in P51, but, perhaps, taking more time to complete than with 190.
I've noticed that Zeke has a impresive rudder authority, so, IMO, this plane is a good candidate to perform this maneuvre very quickly.
