Creating a Wrecking Ball using Spring joints?

Hello, all. I'm trying to make a Wrecking Ball attached to a long Cylinder object(the Wire), both of which are Rigidbodies using gravity with Spring Joints targeted to the parent objects. I've been able to attach the ball to a crane object using a Spring Joint without much issue, but when trying to do the former, I get all sorts of physics issues, making them all look jittery. The object hierarchy is: -Crane -^Wire Object -^^Wrecking Ball
