My bloods are either in their hides or burrowed in the substrate. I have never had one show interest in climbing. The setup you are describing does not sound very well suited for a blood python and is not addressing the question of the op. It sounds more like a setup for a arboreal snake.
Do your bloods climb?
If this is the setup you are using with them post a pic. I'm interested to see it.
I keep my big girl in a 48*24*15 pvc cage and have three smaller ones in a rack system.
