I've done this cross several times. True, at the current prices it doesn't make much sense but when I started 100% het pied males where thousands of dollars. Also, with pied you have the het indicator bellies some of the time. Some don't put much stock in that but I do. I can't really prove anything yet as very few of my hold back het pied bally females have reached breeding size. Just last year I held back this girl who if you follow down her linage only is on paper a 12.5% chance het piebald.
