Hello all, Noob here I have a question in regards to a scenario..here goes: Rope bag is tossed and I do not hear it hit but decide to roll over ledge anyway and it slopes and I cannot ascertain that rope has hit bottom. I get over slope lip and then notice rope never hit deck and am dangling, deciding to ascend or tie other rope to complete rappel. I decide to tie other rope to complete rappel, passing the knot. What knot? EDK, Figure 8, etc?
