I can see where this thread may be turning into
-don't do low level acro vs do it
-don't do it in warbird vs. do it
-don't fly them vs fly them
-etc
However, I agree with Randy regarding the view that there is always risk. My take is that it is about an individual (or organization) properly managing the risk. I have no problem with the right person doing low level acro for the right reasons (ie; a defined act within a show, or practicing toward ultimate goal in a staged approach,etc) with the right training, mindset, and mitigation of outside factors. Make yourself clear rules regarding your own defined limitations, and stick to them.
I think that's a key element- make yourself promises you won't break.
It seems the improptu, unplanned actions bite people.
I stick to the higher altitude acro, but that's simply my comfort zone that results from an analysis of myself and my safety limitations. I accept the fact that others are in a different place in their own self analysis and equipment, and can handle low level acro.
