Forgive me for being ignorant - to summarise you should outcross by beeding an AB with a Pit ? or have completely missed it all ?
Now im not saying you should, but the topic is about the benefits it can bring correct me if im wrong.... which is where the doubt about the purety of the AB comes into play.
Surely an ABxPit would look nothing like either dog, how can you then present it as one or the other ?
