The wow was because u had a chance to use some dif ch/rom blood for free and u did not even do it to see what wld happen cld have made some of the best dogs ever but will never know. But sounds like you run some of the best blood in the world so I guess u did not need it. But u right to each is own I have my blood in NC,NY,SC,Fl,and MI and they love it!! But like u said each yard is different.
