my initial PPL instructors were all ex military, and not one, (same school) suggested using rudder at the point of stall, my current instructor still teaches similar as i was taught in the 80's at the stall, first action.. regardless of wing drop, or not, is Unstall the aircraft. release back pressure, (not push it either) to gt the wing flying, then roll out of the wing drop, and recover to desired attitude. i was reprimanded until i could do it without losing 50 ft if the wing dropped, or 10 ft in a straight and level stall.
i still practice regularly to this day...
