I don't like inbreeding at all. I think the reason the walker breed is so much stronger than others is because we don't breed as close as others. Sure we linebreed often but not near as close as other off breeds. See a couple links I found below. They are pretty scientific they may not interest some.

"Development of highly productive inbred lines of domestic livestock is possible. To date, however, such attempts have met with little apparent success. Although occasional high performance animals are produced, inbreeding generally results in an overall reduction in performance. This reduction is manifested in many ways. The most obvious effects of inbreeding are poorer reproductive efficiency including higher mortality rates, lower growth rates and a higher frequency of hereditary abnormalities. This has been shown by numerous studies with cattle, horses, sheep, swine and laboratory animals" (missouri.edu).
Animals are no different than people so any time you breed to tight for too long you will have genetic abnormalities. I would advise anyone against it, but than again its whatever you like.
agian, inbreeding or linebreeding didnt INTRODUCE these faults/side effects, they only condenced them so they were brought to light. there would have also been the exact OPPOSITE side effects in others in the same offspring pool.......long story short, inbreeding brings out both good and bad, you cull the bad and continue on with the good......sooner or later you have removed the bad and only the good is there. think refine.....
there is also things to be said for outright outcrosses of course, hybred vigor first and formost......however outcrosses can never produce a true purebred, only hybreds.
