I started the same way as you but with only one ball python. I then wanted something different, not too big, etc and settled on a Hog Island boa. He is beautiful and now is about 4 1/2 feet long (strong as an ox almost too strong for a neck snake but still fun). Then I found a young Jungle Carpet and she is a character - much more curious and mobile. She loves to hang from a dowel in her enclosure and she lives there basically, only using her hide when shedding. I also have a Brazilian Rainbow and he is a great guy - growing like a weed though. He is not only beautiful but has the smoothest scales that I have ever felt. I wanted a variety so I could always have one to handle (not shedding or eating) plus they are different in their mannerisms. They are all handled frequently and are very good to deal with but if I was to get another or get into one species I think that it would be the Jungle Carpets. They are beautiful, easy to feed and after initial nippiness are a great snake - my little girl is not as thick as my other snakes but fairly long with a very long, thin tail.
