Couldn't agree more - both that it's harder to spin than most think, and that spinning should be experienced at some point. Pretty sure nobody said don't, but don't go and do this on your own. 90% of folks have no idea where the edges of the envelope are, or what they feel like, which is both a waste of capability, and in my opinion dangerous.
However, this is another pprune debate which borders on holy war. Expect someone from the anti-spinning brigade along shortly using words like 'macho rubbish', etc.
