More generally, anything relating to simulations in which something presses against the outside of the cloth (e.g. belts). The cloth room seems biased towards collisions occurring against the "inside" of the mesh, probably with good reason. I've had only moderate success so far, and that was by continually going round this loop: simulate until it breaks; export mesh; repeat until fed up. :)

Also, your thoughts (if any) on the merits of Delaunay triangulation for cloth meshes. I've heard it's pretty good, and had read an article on Delaunay-ising an existing mesh using Sculptris, I think it was - however that was at the old DAZ forums, I believe, so no link at present. :(
