I get where you're coming from. We have 6 BP's and they're awesome, but I don't feel a strong urge to add another. We also have a corn snake and 2 boas (Dumeril's and longicauda). The boas are sooo cool. I know my limits, size-wise, and a CP would fit right in. And I love the idea of a semi-arboreal snake. The zoo we go to has Carpets in the Australia building, and I love looking at them.
Also, I've followed Yafe's threads and I'm so happy he seems to be doing better!
