I love collecting tricks with just the 4 aces, and one of my favourites is Sanverted from John Carneys Carneycopia book and on his Chicarnery dvd.
This routine is a variation of Sanverted which I learned from Dan Fleshmans - Every Table is a Stage DVD (a routine called Daley/Hammond Combined). The squeeze I give the packet is my homage to Michael Skinner who always added little touches like that.
I like this version as normally people end Sanverted with a Daley-esque ace transpo, however I feel this one has a stronger kicker ending - plus most of the time if I'm performing for someone I'll have done some sort of Daley transpo already.
