You've basically written a dealer ad for yourself. Dealers tick off long lists of methods not used in ads because many hobbyists are disdainful of the simplicity of the secrets they know.
You learn a secret and you think "that's it?," and so begins the chase for a secret that is going to live up to the satisfaction and excitement of the illusion it creates...
There is nothing wrong with that as a source of amusement and a personal hobby. Now, however, you are talking about performing -- sharing magic with real people. Once you take that step, it is no longer about the methods that entertain you.
The Hoy trick is fantastic. It is also, as the book title suggests, bold. To perform it well requires a certain amount of confidence that best comes from experience. If you're preparing months in advance for this particular show, I'd probably steer clear.
A very practical option is Bob Cassidy's Impromptu Book Test (you can find it in The Artful Mentalism of Bob Cassidy) ... and I would also take a look at Roberto Giobbi's excellent work on the riffle force...as some of his finesse applies to this piece
As you're playing this as a prediction, you'll need some time alone with the book beforehand to decide on a force page and prepare the book so that you can effortlessly access the force page during performance (I have never performed the Cassidy piece as a prediction...so this is just hypothetical...but an approach I would try would be to short the page prior to the force page...you could also, if you preferred, use the short for the actual force...I like the Cassidy/Giobbi handling I use)
The variants of Barrie Richardson's fantastic phone book test would also work...the best information, in terms of actually doing this in the real world for real people, is in Bob Kohler's The Human Phone Number...but the investment may not make sense if this is a one-shot deal...
Maurice Fogel's Headline Hunter could also fit your needs...there is a phenomenal Barrie Richardson piece in Theater of The Mind -- the name of the piece escapes me and my library is in storage while I move -- where a chooses a piece of newspaper, closes here eyes, and lets a word "float" up to her...could be easily used as a prediction and fits all of your method requirements...I haven't done it or seen anyone do it, but it reads very, very strong
