I don't use wire rope slings much, mostly synthetic, but I might have to. For an eye and eye sling, it seems like my basic choices are either a Flemish splice or a loopback eye. OSHA doesn't require proof testing of either, but loopback eye slings built to ASME B30.9 require proof testing. Loopback eye slings built to EN 13411 don't require proof testing. The internet tells me that they use gauging to determine whether the crimp is correct and that there are failure modes that the gauging will catch but the proof test won't.
What are the relative advantages of these two options? Pricewise they seem similar. Is there a good reason to pick one or the other?
