Solid Sling vs Link Connectors

Hi All,


I am using a solid lifting sling to lift a frame (its a 4 legged lifting sling), connected to one single lift point above, as shown below. I am having stability issues, even after applying elastic supports at the bottom + applying soft springs to stabilize the model (via checking the option in properties).

I then tried to model the lifting slings with link connectors, and the simulation converged.

My question is that the solid lifting sling is more realistic as it will flex and apply tensile load in the lift pad-eyes. But on the other hand the link connectors are just "rigid" connectors and will not move. Any advice on which way to proceed (or any other way to model), to find a accurate solution?
