Yes yes, dredging up this thread again! I've started to use the faro on people now. I've worked out a nice effect where two cards are selected from a deck, and replaced in such a way that by the end of the trick, the deck is in order save for the two cards which have now swapped places.
I really enjoy doing it, mainly because about halfway through the patter it appears that the trick I'm doing is just me fooling around. Once the cards are reintroduced, I shuffle the deck once or twice (depending on how I feel) click my fingers and then announce that the cards have changed places. People sometimes visibly slump when I say this. I'll sometimes even quickly fan through the deck to "show" that the cards have swapped. So not only am I a fool, but the deck is "genuinely shuffled". I then say something along the lines of "well, I can see you're not impressed, and maybe even that you don't believe that the cards have changed places at all. It looks like I'll have to prove it to you." I then run through the remaining shuffles, ask them which cards they chose, and fan through the deck to show it in order with the two cards switched.
Asking the specs what cards they've chosen is important because (and with disturbing frequency) they may select two mate cards, or sequential cards. When this happens, the fact that they have swapped isn't always obvious. Also it serves as a slight misdirection. Does the 'gician switch the cards the second he hears what they are? Now that's a skill worth having!

And the re-ordering of the deck is a more impressive feat than switching the two cards, which gives the reveal more prestige.
The only real danger with it is that if you're cutting to the 26th card by glimpsing it and having the 26th card sequence remembered, there's nothing to stop the specs picking one of the sequence cards. That's why it's handy to have a decent understanding of what the surrounding cards are, which is fairly easy to grasp. If you're smooth and confident enough, of course, when you see a card sitting where a sequence card ought to be, you'll know what the two chosen cards are, so rather than ask the specs, you can tell them which cards they chose (though obviously not necessarily who picked what).
There is another method for this trick, but it involves having 2652 decks hidden about your person and very smooth switching powers. You can PM me for the index I use.
