Okay, first of all, looks like you are really into learning moves and you dont have the chanse to perform a lot (outiside, to people you dont know) I hope Im wrong...
Anyway,if there is a book that I dont tire of recommending its Aaron Fisher's "The Paper Engine". It has some pretty good sleights along with some very deep, with patter tricks, I know you will like it.
