I would suggest you should approach this question from a different direction.
Assuming we are not talking about aerobatic training, I think it is imperative that one does not think about the stall entry as a stand alone exercise. There is no reason the aircraft should stall at altitude. If the aircraft has stalled than the guy/gal at the controls has seriously screwed up and if close to the ground this is a full blooded emeregency. Therefore it is vital that the instinctive reaction of the pilot to a stall is to lower the nose to unstall the wing and to simulataneously use all necessary rudder to stop the aircraft from yawing thus making it impossible for it to enter a spin. In training the worse the stall entry the better as if the student can reliably recover from a banked yawed entry than they will be well prepared if they ever get cought for real. Finally the best recovery from a stall is to not stall in the first place therefore training to recognize the condition which indicate a potential stall is possible is just, if not more, important than stall recovery training. Stall entry training is simply a necessary precursor to learn the real lesson, stall avoidance and recovery, and should never IMO be presented as an exercise in itself.
