When I use orient constrain they joint flips on its side so that its lying parallel with the curve, which is not really what I am after. What I am really after is to have the spine and each joint of it can be rotated by grabbing the curve, but when I try this like I say it either flips on its side, or sometimes just spins really really fast when I move the rotation too just a tiny bit. I am confused lol!

Plz send wise words this way!!

Cheers
