I like my ball pythons, I like my corns, I like my rtbs, however I have grown to LOVE my dumerils boas! They are heftier than the average rtb while not getting really long. I would recommend getting a male dum. They tend to run a little smaller than the females. The can get 9 feet but that is a rare occasion. They seem to average 5-7 feet for both males and females. The have very mellow attitudes and do great taking f/t . They also grow at a painstakingly slow rate so depending on your age you maybe out on your own before it ever gets to full size if you purchase a baby. Good luck on what ever you decide on.
