Found out this weekend the practical truth in what MADD777, an engineer, had been trying to politely explain about the stresses we impose on our suspension systems. The weakest link in your system will put your behind on the ground. My Single Line Suspension (SLS) failed at the tree hugger loop. With the crack of a 22 cal rifle I was on the ground! The amsteel was adequate for the loading but my DIY stitching of the loops wasn't. Physics will find the weakest link in any system resulting in a failure.
Lesson learned. Overbuild for sucess or hang close to the ground for the inevitable failure.
