I personally would like to try it at least once, but with only myself in the plane and not for a couple of thousand more hours yet. However although I'm not the sort of chap to thump people, I probably would if somebody did it to me. While I'm sure it has some benefit as a training exercise (which is why I'd like to try it) I can't help but feel the minuses more than outweigh the pluses.
