Some interesting points there Centaurus. This touches on something I have long discussed with instructors, and that is, why do they only practice stalls with power off, or at most low power settings? An aeroplane can handle quite differently with full power and low airspeed in the stall for many factors, and from personal experience, I have found that at airspeeds closing in on the stall, I have been at full noise.
As for the whole idea of letting a TIF student have the controls first takeoff, I am no instructor, but I always had things demonstrated to me before I would try it myself.
