I breed tight two or three generation, then outcross to one of two types of dog. Outside blood that's tight bred or an outcross dog from my line. If I like the results I breed tight again from there. A female provides only 50% of the genes but truly great females are a true treasure. Personally I don't think line breeding is an end unto it's self but a way to produce THE outcross dog that can be bred to most any solid producer to produce high percentage, high quality litters.
I like this style as well...but I will inbreed to the right dog...
