In all the aircraft I've spun, we have entered by (full) aft central stick and (full) rudder deflection.
If the aircraft is being flown close to the stall, with the stick a long way back to minimise or stop the descent, then how can using rudder at this time be an advisable action? Surely these are the exact control inputs a pilot needs to make to enter the spin? If wing drop has occured, then the aircraft is stalling and a recovery should be initiated - using rudder here will surely make the aircraft more unstable and likely to depart.
JF this is not a criticism of your advice, I just can't see the benefit of using rudder in a stall to avoid spinning!!
