Absolutely, i simplified the issue i was having down to just the sample scripts to make it easy to reproduce. I've got a set of projects with different spline and softbody implementations, i'd just seen the snake not work when i brought it into a softbody scene and assumed it was the contact not recording, hadn't tweaked to traction being a finite list.  

Thanks for your help mate
