On the flip side, I 'spect if one rolled in full nose down manual trim for recovery, one would have a tiger-by-the-tail when and if the stall broke at some 30 or so degrees nose low and accelerating with a limiting 2.5 g available.
Yep, I agree. You would ideally like to dial in a 300 knot trim setting, and only if you absolutely needed it to break a stall would you go to a lower trim setting. But them you better have PNF primed to dial it back pronto as soon as the airspeed begins to accelerate past 200 knots.
Probably better to rock the aircraft out of the stall than to dial in those last few nose down units. More than likely, it would be a quicker and more positive recovery.
