no matter how many 4 ace productions I do, the one that always gets the best reaction is the jack, queen, king, ace cutting that he does in his final effect in "Card Stunts". I do it with the four aces, and just cull them in a borrowed deck.
It always shocks and awes, and is done very quickly. Nothing I have done beats it when I do it myself, unless I get them to do it instead, and cut to the aces themselves. But thats not what you are after.
Good dvd to check out on the whole as well - especially the effect "The Boomerang Card of Death"
