The Masters of the Bare Bow series (in particular No. III) are terrific. However, by reading books by G. Fred Asbell, Brian Sorrells, Byron Ferguson, Jay Kidwell, etc., you will find a lot of different ideas or techniques to try to see if they work for you. Part of the fun of all these books and videos is to stop in the middle of reading or watching and try something to see how it feels.
While there are a lot of thoughts on equipment and form, you will also find many things that are repeated across most sources. Just like repetition in shooting, repetition in reading/watching helps drive certain points home.
