When it comes to the method breeding up I do recommend being careful as some strains are so line,bred tbat when they cross out you may learn of the "dark side" of the strain :P
:thumbsup I am going to be breeding offically Swart Honas, using three out of the four birds I own so I plan on using line breeding to develop my strain until I aquire a good quality rooster to sire a secondary line.
I myself was given that book and I suspect that even within the concept of line breeding people have different "views". Myself I would probably attempt to either meld the methods or use one that looks the most appealing to me.
