To the original OP, here is a list of the current ABC All Age standings. It would behove you to try and find a dog out of one of these dogs. Better yet, try and get a dog out of the dogs who produced these dogs. That's going to be your best shot at getting a great dog. I'll also post a link to the AA Nationals as well. In the link you can see the dog info of all the dogs running in the Amateur and Open nationals. The dog info link shows the sire and dame of all the dogs running. Study that well and look back a couple of years to get an idea of the dogs who are producing the top dogs. There's two or three breeders on the West coast who are breeding top dogs, but as far as I know, not many will be roan. There's a breeder in ID who is breeding a dog who is from the same lines of dogs who have been doing very well on the AKC circuit. One of those dogs is the reigning Purina AA dog of the year, and currently the #1 dog in the country. It's a very good line of dogs, but you will see very little roan in them.

If your interested, PM me and I'll give you the name of 3-4 breeders on the west coast who actively participate in ABC trials. One of them does occasionally have some roan dogs, and her dogs are typically dual dogs.
