I had a Contendro filly this year, out of my Phantom/Polydor mare. She is a keeper for me. Of course, I can't tell you much about her work ethic, etc., b/c she is just a baby. However, I can say that she is much more refined (at this point) than her dam. She also got a gorgeous head and neck, probably from her sire. This same mare has had a Cassini II filly and an Indoctro filly and of the three this one is definitely the most feminine and typey.
Can't comment on size yet, although she isn't small for her age at this point. But the mare is 16.3, and long-lined.
