I purchased one set (can't remember which) and didn't find it helpful. I cannot recall the editing one way or another - I know some of his books have been poorly edited but I still understood the message and, like you, I have a number of ppl to train with in "real" life so the books have only supplemented those things I learned.
You know, if you are interested in a flash card system that was really effective for you, it may be best to sit with your teachers and get them to go through things while you take notes and then make your own cards. Would probably be more effective cos you would know your own shorthand and the areas you feel you are weaker in etc.
Out of interest, how long have you been training for? (just for my own curiosity )
