Ahhh. Thanks you so much Christian. I've been wondering about this for quite a while now. Nice to have that cleared up.
Just out of curiousity, which do you think is better?
Yes the cardini is a more "bam in your face!" change because it happens so fast. I love it and use it all the time, it gets that "what the...?" factor for me. (took me forever to get it down as well as I do now.
)
The ego, from what I have seen on performance and practice wise, is more of an updated erdnase change. Danny explains it by "rubbing your hand over the card as you change it." This, to me, builds a bit more suspense for the audience. If you watch Danny's performance of ego (can be found on youtube or wherever), he covers the card and it changes, once his had is removed, the spectator reacts with a nice reaction because he is not sure what is going to happen then the change happens.
In terms of 'better,' its hard to say. I like the cardini, but thats because I have it down better than the ego. Its also personal preferance. The ego, from what I've heard, is "slower" than the cardini. The angels seem the same, but I could be wrong on that. I would play around with both and use the one that suits you, and it could be both of them, you never know.
Hope this helps!
Your boy,
