I have acquired a used HH Expedition. It is my first Hennessy Hammock, and I have not yet set it up. There are some pieces missing, and I have to wait until I get some tree straps.

The internal ridge line is untied on one end, it is the same line that the mesh organizer is attached to and slides on. To repair this line, do I have to remove the "sock" on the gathered end and untie the gathered end?

Is the ridge line even necessary on this hammock? It looks pretty flimsy.
