Rope vs Cloth

[arkanis]

So I've purchased Rope, Cloth, and Fluid as I have use cases in my simulator project that will need all of them.

A simple question here, for a Tourniquet like this: 



Would there be any advantage to using cloth vs rope? They are not very flexible on the shorter axis, mostly just on the longer axis, so I'm thinking it might be computationally less expensive to treat it as a rope but I don't really know the underpinnings of all the systems.

Thanks.
