Mike,
Maybe some of us were just out flying and didn't stumble on this until now

As you said (I think) there are many ways/variations to do these moves. for the wall, I like enter at idle and blip the throttle to get a really quick rotation. By blip I mean hit some throttle and back off immediately to keep the airplane from climbing. I have found this kind of throttle motion sorta pastes the plane to the sky. Then Its whatever is to be next. If I want to hover or TR I'll smoothly but quickly add throttle to the airplanes' required hover throttle setting.
