I have seen many references to a book called BTZS or "Beyond the Zone System", and the general consenseus is this is a great book. Does one really need to learn the zone system? Can one step right into BTZS? If not, does anyone recommend a book on the Zone system for one who needs to learn it? A easy reading book not filled with a lot of dry tech talk, meant to lull one to sleep (thats what college professors are for). It's not for me of course. No it's for ... um... for a friend.
