Well cards are my bread and butter, but I want to branch out into coins and many other areas. However, I want a much greater sophistication and understanding of card magic which is why I emphasize that type of book. I do not currently do any gambling effects, but that is one area I want to become proficient at. Well I typically like performing effects with simple gimmicks such as a duplicate card, double back or double face card. I definitely am looking for effects that would include these types of gimmicks as I do not want to have my pockets bulging because of the gimmicks; I am open to other small gimmicks as well. The best way I can explain as to what books I am looking for is that I want to have the equialent of a PhD in my knowledge of card magic. If this includes having books that include types of effects I wouldn't perform, that's fine because I would like to be knowledgable of many important aspects of card magic. I tend to do very direct effects. I do walk around style mostly, but I want to work on formal close up shows as well as stage shows. I hope I have been clear enough, but please let me know if I'm too ambiguous!
