Because there's so many allies with Batman, I'd really like to simplify things...the big three that I'm focusing on are Batman, the Robins, and the Batgirls. As I'm reading Bat's story, because those three started with Batman since the beginning, I felt like it would be simpler. I mean if I don't really have an interest in Duke or Harper. But I do know they pop up in the book from time to time.
