Just a word of caution. Full opposite rudder (not all aircraft require it and in some it may make things worse) without simultaneously relaxing the backpressure will only result in a spin developing in the opposite direction. You must reduce the AoA below the Critical angle with elevator and stop the yaw with rudder at the same time to effectively stop the spin.
COMPLETELY disagree-
Standard spin recovery-
1) Opposite rudder until rotation stops
2) Relax back pressure
3) Recover from the dive.
In a high performance aircraft, what you advocate is a recipie for the "Dead mans spin"- that is, forward pressure simutainious with opposite rudder has the potential to put the aircraft in an INVERTED spin in the opposite direction.
The danger of this is that an inverted spin in one direction is very hard to distiguish from an upright spin in the other. It is extremely disorientating as it appears that the aircraft has simply not responded.
The first aircraft I ever owned was a Pitts S2A. A subsequent owner was extremely lucky not to die after crashing through trees after a very low recovery due to exactley what I have described above.
