first of all it's good to hear u steve, needless to say your opinion is highly appreciated. Now about my point.
I talked about this episode with several pilots (a couple of military pilots and a pitts one), and they all gave a different opinion!
When I say the climb was too steep I meant that the eccessive loss of kinetic energy was caused by an improper climb or probably by a low speed start..
I was always told that when u find yourself in a critical flight attitude u dont have to follow your instinct, but u must second the plane attitude for a second to understand what's really going on (I've never found myself in an inverted spin, but I guess it's not the best place to be..). An improper input might put yourself in a more critical situation.
I've expressed my opinions according to my really modest experience and about what I was told by professional pilots about the matter, hope I made myself clearer!
As per the height or energy question, well this is a matter of opinions. I agree with u that performing a correct aerobatic display would be the solution, but I guess u need a safety layer just in case u make some mistake, dont u think so?

P.S.
About the loop. If u do one with your Sea Fury, but u lose almost all yr kinetic energy on your way up, and u reach the top of it at full throttle but almost zero airspeed, doesnt the prop torque affect the plane behaviour?
