If you're looking the flourishing kind of stuff then Steerpike's suggestion is right on the money.
If, however, you're looking for more of the classic back and front palm production-type stuff, then Lewis Ganson's Routined Manipulation series contains all the classic moves and there are a few fanning texts like Ed Marlo's Card Fan Productions. These books will pretty much just go over the areas you'll already be familiar with from Dan Sperry's stuff, though. This is one area where all the new stuff is on DVD. Lukas and An Ha Lim both have DVD sets out which are well worth checking out if you want to learn some new moves.
