xbar - I have chosen to do business with people I respect and trust. If I do not trust the owner/breeder than I question the authenticity of the animal; pedigree, bw, ww, etc. It is a personal decision. If a person is a liar and cheater, how can you trust the animal is actually honestly represented? I can not, so therefore, I have chosen to stay away from such animals. You can make your own choice.
I and my checkbook have walked away from plenty of good animals due to their owner/breeder. And I will continue to do so. Too many good animals owned by good people to deal with "butt heads".
CAB - I have chosen not to use red angus that are offspring of black angus. If I wanted to breed black angus, I would raise blacks and not reds <beer>. I do realize that red angus did derive from black angus way back when, but to use black genetics now, just does not make sense to me. New Direction does look interesting but I am not a fan a Mytty in Focus, so.
Strictly a personal decision, and each can do as they see fit for their operation.
