Good Conformation =/= Looks like a Quarter Horse. (Unless it's a Quarter Horse or a Paint that is)

Good conformation includes proper balance and mass, structural correctness and skeletal structure that promotes lasting soundness. It has nothing to do with quarterhorses.

There is not a lot of difference between these two horses at least IMHO not enough to poopoo on injecting a little different blood sometimes. You can do just as much harm to a gene pool by never introducing new dna into it.
