Sounds like a little bit of magician's guilt there; whilst - in terms of blocking out the performance - it does seem 'suspect' to *us*, I've never had this questioned by any spec so far (and I've used it bloody loads so far!).
As far as I can see, the specs' view - in terms of the way I ruffle through the compartments in their wallet - is simply that I am locating the card more quickly than they could, and then letting them do the final reveal.
Still, it's nice to have multiple uses available from one, simple gimmick, whicever one rings your bell!
