Years ago, I owned one of each. Both were rather aggressive and would come out from hiding and strike at the glass everytime someone came near. I was unable to handle them, so I got rid of them. Beautiful snakes though.
If you buy a hatchling make sure its already feeding well on rodents as they can be tough to get started. Sometimes they need to start with feeding on skinks or skink-scented rodents. Other than that they keep like any other AUS python. Can't comment if they are like balls etc in their husbandry as I can only keep natives so don't know much about others.
