Yeah, when i first learned the ego change that's pretty much what it looked like for me.. but then i watched the video again and i realized that it was supposed to be a much slower more "just wave your hand" kinda thing.. If i was you i would go back and re-watch the performance and explanation again... I really think that a well done ego change IS the one of the highest impact color changes to a layperson.. The Cardinin change is good, but it looks, to a layman, like a "move" where as the ego looks like real magic.. so go back and re-watch the videos..
just my thoughts, hope that helps...
