I would breed him to a snake of different lineage for sure. The only thing is finding one that you know for sure is genetically what you need. It's a shame a few wc specimens can't be harvested and used for breeding programs to get fresh genes into the captive gene pool and then release them. Also releasing cb snakes to boost up the populations would be nice if it could be done safely. (Disease etc)
Beautiful snake you have there in any case. Good luck.
