Character Joints, twist and swing

First, I should mention that I'm working on trying to make a 2d character ragdoll. Getting started was fairly simple, I used the ragdoll wizard, constrained movement to only the x and y axis, while restricting rotation on the x and y. It works but joints are not realistic and swing in any direction. This is understandable as I haven't properly set them up. I feel like I've tried playing around enough with the swing and twist limits, axis and swing axis settings. Nothing seems to work correctly. More strange is, I set up say the knee joint, it works as I'd expect, I then set up left hip joint and it works nothing like I'd expect. I'm even using EnhanceCharacterJoint.cs by dmorton and EnhanceCharacterJointInspector.cs by masterprompt found here http://forum.unity3d.com/threads/24931-character-joint-swing-and-twist-axes, this pair of scripts give visual representations of swing and twist limits, I still can't get this working right. The joints will swing out of range of the limit I set. My question is, how can I set up these characters joints properly for a 2d character ragdoll?
