For example, many people said that RBJBT is a battle cross. But say in the case of Evo where most of his dogs are RBJBT and he built a line off of them.

1. Does it then becomes it's own "bloodline" or is still a cross?
2. If let's say we add a little bit of Eli or Jeep into it (like an out, back in the pedigree) is it still RBJBT or now does it become a new cross (RBJBT x Eli x Jeep)?

Hope Jack or anyone can clarify this.
