I agree that its all about the money. What is winning in the halter world at the moment, what is making all the big bucks, and what is selling for the most money, are the Impressive lined horses, because they get that muscling that people seem to want, and to them for some reason its worth the risk, and even the dealing with the horse that may pass it on, or that may have the sickness. I know a lady who used to do halter horses, her gelding she gelded specifically because he tested N/H, and she didn't want to even potentially pass it on to another horse. Its as much the show judges faults as is the breeders, because since that's what is (or was, its been a couple years since I've really looked at the halter world), what wins the shows, and is what the judges are looking for, its what the people are going to breed. I still think its sad though that people are willing to potential get an animal with the disease just because they want that extra edge in the show ring, and aren't willing to breed lines that don't have the disease, or can't pass it on.
