Well said 421dog...The throttle back hands and feet off everything will work in your average spam can, whilst it will recover from the spin, you will inevitably end up in a dive approaching VNE and probably wings not level, now this is a situation that could have been avoided if trained to recover in the correct way.
How many low hours PPL's would have the courage to let go of everything anyway?
How many of them would recognise, in time, that they are approaching VNE?
You would loose a lot more height in this situation.
Even this is not taught in the PPL syllabus, confidence and reaction are the key words, you can only get that trough proper training.
