Trying to Continue a BJ Legacy

My father is a counter, and I grew up around the game. He was on a team when I was young and now that I'm old enough I've been sitting with him to help the spread as a second seat. I play a perfect basic strategy and have even developed a feel for the "pull" of the count (i.e. I know when to look for his signal to deviate from Basic ) I've been trying to learn the hi-lo count from Revere's book (Playing BJ as a Business), but its old and I'd like to find something that deals with a six-deck game with AC conditions. I think it would be a great Father's Day present to be playing with him one day and lean over and whisper, "I've got a running 18" and be right. Any suggestions would be greatly appreciated.
