Years ago I called Samson Rope to try and get the test criteria for their 60% rating. They could/would not provide me with actual test data. As I told another forum member, Samson Rope is a large corporation whose products are used on far heavier loads costing much more than what we do. I believe they are very conservative with their ratings as they should be in today's legal environment. I told Samson what I do with their 7/64" Amsteel Blue line and they stated that the sling should rating 90-100% of the line strength. We tested many slings with a 1600 pound static load and all held just fine. Some were even tested with additional weight without failure.
Remember that whoopie slings originated in the arborist/timber industry where the dynamic loads of a large log being hoisted out of a forest are much different than what we do. I wonder if Samson make have taken that into account on their rating?
The use of 7/64" Amsteel Blue for hammock suspension has not been an issue when properly constructed. Good advice from Detail Man as to always inspect your gear and replace at sings of excessive wear or damage.
