Yes - agreed the Immediate action of pitch down is far more important.
As an experiment after this accident I took a G115 up to clear airspace Nr Clitheroe and set up a climb at 4000' in the T/O configuration at 68Kts. After carb heat I throttled back and tried to maintain the climb attitude to see exactly what happens.
Suffice to say I counted literally to 3 and the aircraft stalled immediately with hardly any 'conventional' warnings and entered a hard wing drop to the left- although I didn't allow it to start spinning.
The main lesson was how it differed from other stalls that I'd tried - it just stopped flying basically - the aggressiveness was surprising. At 300' you'd have no chance.
That was my main lesson that I still remember.
