Try to get hold of Dingle's Paris Super Sessions video. He performs it on that. I'm not saying you should copy him, but it is worth watching to understand his timing.
The effect goes back to Edward victor; it is interesting how many of the 'classic' effects need a lot of thought about their presentation. Cards up the sleeve is another one; you have to sell it right.
does this mean that, really, they are too long and irrelevant for a modern audience?
I do wonder; after all, there are very few magicians today who could entertain with, say, an eight ring routine. Attention spans are shorter.
Then sometimes I think - it is like Shakespeare v Friends? Friends is undemanding, but Shakespeare more rewarding. But then, Shakespeare's comedies, to me, are as unfunny as the unfunniest sitcoms....for me, their time has past.
Sorry, I'm rambling. Too many cards can still play well. But, like with all magic, once you have developed the technical proficiency, you then need to learn how to present it. and you just need to view Fred Kaps performing the Homing card to know what i'm talking about.
