having occasionally done this stunt for a few years, i'm gonna have to agree with both previous statements. i've accidentally nearly tagged my brother in the face, and i've had people who didn't hold their hands together strong enough, such that i only got enough of a step to do a half-rotation... and land flat on my head. i still remember that- my neck was stiff for the rest of the day. seen some people who couldn't do just the standing back, and could successfully pull this one... sometimes the extra height was all it took to get them around. still, make sure you practice this on something other than concrete.
