softbody breast help (Solved)

I have a character rigged up everything is working problem is whenever I make softbody of breast they go haywire I have tried the same with a ball before and got a good effect but on my model everything just goes crazy the breast do have bones for fine tweaking if I need it but for most part I just want the physics engine to do the work file below so I guess what I need help is to make it look natural pictures below of what happens when I add softbody please help.

no soft body

with soft body

I fixed this issue by adding a plane soft body then having the bones track the moving soft body points and it works really good here is the file
