If you're planning on shooting for a hybrid, be prepared for failures upon failures before a success (if that ever comes).
Often times these attempts end up with clutch after clutch of slugs even if you get locks to happen.
My 2 personal rules for hybridizing:
1) Only hybridize snakes that are significantly visually different. Burmese x balls, woma and burmese x balls are two that are very unique looking and will never be mistaken by anyone who knows snakes as either contributing species. The ball x angolan however.. someone could feasibly attempt to flip one as a "new" ball python morph. That is the problem most anti-hybridizers picture 'destroying the hobby'. Even super balls as adults look very blood python-esque to the point where one might be mistaken as a non-hybrid.
2) never shoot for 75%ers, or in fact ever breed hybrids (even to other hybrids). The risk of creating an animal that could be mistaken as a non-hybrid is too great. Hybrids should not be investment animals, but a pet/display animal. It sucks that this hobby is so focused on animals as potential breeders, because then we wouldn't quite have such a controversy with hybrids.
I would love to have a wall or burmball in my collection someday.
