Craig,
Glad everything is going well with your girl.
I only have one CP, Yafe, and he's a sweetheart. However, I hook trained him and still use the hook every time I pick him up. I do the same for the three boas.
CP's have a strong food drive and although it might not be an attitude issue, you don't want to get nailed.
My rule of thumb is all my animals that get big enough to hurt and/or have a strong food drive, get hook trained and I use it every time I pick them up, for life. They've all gotten used to it and know it means handling time and not food time. It also keeps you from accidentally waking them up or spooking them.
Additionally, in the case of Moreila, to gives them an alternative to grab onto to come out as opposed to your hand and untangling them if on a perch.
Just my two cents.
Again, very glad she's doing so well and calming down so quickly.
