My JCP, Esmarelda was a year old when I got her. She has never bit me or struck at me.
My BP spends at least 50% of her life in her hide. My JCP never spent any time in her hide whatsoever until I mounted a hide on the ceiling. Now she goes in during her shed or uses it for hunting.
She also never ever spent any time on the ground under until I got a new enclosure with belly heat. She uses it for a day or two after meals. She used spend all of her time on her perch in her old home.
Now that she has a forever home with many options she takes advantage of all of them.
You will need to up your handling game when moving from Balls to Carpets. But it is not difficult by any means.
Esmarelda is at the top of my favorite list. Being highly arboreal she is a joy to watch and makes a top notch display snake, which is why I have afforded her the largest cage.
Best of luck with your research, I trust that you would be quite pleased with a JCP.
