It looks to me that Barry's question was something like does a plane with light wing loading spin "better" than the same plane with less wing loading. I still think if you select a plane that spins well as is , then ballast it up enough to make a difference it will get better, worse, or not change much. Question answered. I would be interested in the answer. I am not good enough to take the pilot out of the test but someone that is really good at spins should do well as a test pilot.
