My recovery from spins in the C150A and C152A was relax backpressure and opposite rudder. No ham fisted flying. The 152 was very docile where as the 150 definitely had a bight. The one thing I remember distinctly (this happened in 1994) was the spin on this occasion looked much flatter than usual. After the event I accurately calculated our CofG and it was just in the rear limit. I have also heard of a similar thing happenning to Cape York Air a few years later in their C150A.
Forky, as mentioned a hard deck in Aero’s is a theoretical level that you don’t go below. Mine was 3000.
