Not meaning to start a disagreement, but using a non-SOP Orpington on a Self Blue to get it to SOP quality may not be a good idea. That is why we are using a pure Cecil Moore line Black Orpington. It just takes time and lots of culling to get where we want in this new variety.
Until we have five breeders that have worked on the Self Blue for five years or more we can not even consider applying for SOP acceptance. Then there must be at least 50 birds entered that are like a cookie cutter of each other. If some are of English type and some are of American type the qualifying judge will just shake his head and say NO. These must be to the Orpington Standard.
What everyone does in their own backyard is defintely their own business. But when we apply for SOP acceptance, every Lavender/Self Blue breeder will have to be on the same page. The Marans folks learned that the hard way. The Lavender Silkies did to. When they agreed to the term "Self Blue" it was accepted. Just a fact of the Standards Committees.
On the bright side, for the first time in history, at Crossroads, a Splash was accepted in the SOP! So there is hope for changes.
