Interesting to note the differences in opinions stated in this thread. Or should I say the lack of standardisation.... I hope that tose who expressed opinions in this thread are Flying Instructors, and not crew-room or back-yard experts. Remember that the aircraft type will behave differently in the stall and / or spin. Follow the approved Flight Manual/Operations Manual.
If you are nervous - tell your instructor. One who is worth his [her] salt will acknowledge the incompatability in the cockpit and get you one who is more compatable. If they disagree - go to a different training organisation.
We were all nervous once, but after numerous supervised and solo stalls and spins, confidnece in one's own ability will prevail - Remember the exercise is about recognising symptoms approaching and during the stall / spin and applying the correct technique to prevent it developing [recovery in theincipient phase] or recovery [for the case of fully developed].
The domestics of the exercise should not be the focus of the brief, activity or the de-brief, as is the case according to some instructors I have met in my time.
Please do not forget the all important LOOKOUT!!!!
