Peter:
". . . while flying an unwieldy lump"

Thank you for that phrase - I will use it often in the future!

For what it is worth, the fully developed spin in the Nimbus 3 is not uncomfortable. The rotation rate is quite slow, the pitch changes not dramatic, and the recovery is reasonably positive. I've about 600 hours in two different N3s. I have never done the spin with water and agree that is the territory for test pilots.
