I've had a few spiders/spider combos and I've noticed this trend as well. Despite their flaws, they always seem to be great eaters and very, very "friendly". They don't really even ball up as much as your typical BP would, are extremely curious when they're outside of their enclosures, and I've never, ever had one strike at me. Perhaps this is a link in their neuro issues. In any case, I don't see how they would make bad pets. They eat, they poop, they do BPs things. They just do them a little bit goofier than your average snake.
I think they're wonderful personally. They are one of my favorite morphs.
