Have watched some rigging tutorials where a simple FK control (e.g. joint1_CTRL which is a NURBS circle or whatever) for a joint is implemented by placing the control over the joint and then using connection editor to create relationship between control and joint rotation axis. ( joint1.rotateX = joint1_CTRL.rotateX ...rotateY... etc... ). Was wondering if it would also be OK, and perhaps simpler, rather than using connection editor expression, to just create a parent constraint (or perhaps orient constraint) between joint and control?? (is there a difference between connection through editor and using constraint???) This would be for FK controls and even some IK controls? Does this violate any rules?

Thanks in advance!
