Depends on how you define an opportunity, to me an opportunity is to add the best example of a mutation in my collection and I am very picky, also when it comes to certain mutations, I like to know what lineage I am working with , while it does not matter to some I like to know what Black Pastel Lineage I am working. (I currently work with two lines)
Other see an opportunity as getting a snake for cheap regardless of what the animal looks like just to be able to say they have said snakes.
Ultimately YOUR choice you are the one that will care for that animal, no one else, and hopefully if you do get this female and decide to breed her to a Black Widow you are fully aware of the possible issues you can end up dealing with.
