I have been considering going to the UBZ II. I know how to use it, but do not have any indices for it. I am not sure I want to go to this system anyways, which is why i am hesitant to purchase the book on it. How many indexes are there for this system, can someon give them to me? I have looked everywhere and can not find the first index. Also is there enough indexes in the book to learn? I want to learn about 40 to 50 indexes if not more. Also, is it better to stick with HiLo and learn more indexes, or go to the UBZ II count and learn the indexes for it (this is assuming there are only 18 or so indexes for the UBZ II system)
