Angolan Python info

hello everyone. Lately i have been looking into buying a pair of angolan pythons to breed together and cross-breed with my bp's to create angry balls (angolan ball pythons). ive searched all over the internet but haven't been able to find the odds of getting Angolan balls. I've heard the chances are slim, but i don't know the exact details. If anyone has any information please help me

still trying to get info on the odds of getting angry balls when breeding angolan pythons and ball pythons. ive heard its a slim chance to get but i want to know if anyone can specify. hoping to get a pair by the end of the year.really want some info on them. anything will help. i know the basics but want some more in depth stuff since the internet doesnt help too much. thanks
