Springs using Interconnect Points blows away?

Hello,

I have extracted the vertices of a mesh and have used "interconnect points" to add springs between all of them. The rest length is equal to the length of the springs. With this setting I expected the mesh to stay as it is when running Kangaroo but the mesh just blows away. Am I doing something wrong?

Many thanks,

Arthur

PS: The aim is to have two meshes with this setting plus a PLaw between them in order to "collide" them. Is that the right strategy for that?
