im all for it, as long as you are responsible enough to keep appropriate records of everything you do with every snake involved in a hybrid project. such as recording every snake another snake has been bred with in the past, so that people know its been bred to another species. lets say you breed a male woma to a female bp, and end up selling the female bp, let the person know that it had been previously bred with a male woma. that way, incase theres any sperm retention and the bp produces an odd looking hatchling by the person you sold it too, they would know that its possibly part woma. and imo, you should only sell a hybrid to people who are responsible enough to not let it go later on as a single species snake. for instance, if you were to have an F2 superball, that doesnt really have any blood/ borneo resemblance, you should never let it go to someone who could possibly sell it as just a cool looking ball python.
