I have a funny paracord story. The first time I went to climb Epinephrine we were really terrified about hauling a pack up there. We hadn't really done any chimneys anywhere near that length before. So we decided we'd take one camelback and have the leader haul it up with paracord so we didn't have anything on our backs while chimneying. It was a massive failure and we ended up hanging it from the second's harness (like we should have in the first place.) But I was incredibly impressed how stretchy 200 feet of paracord are and just how difficult it really is to pull on it with your hands. I think I eventually cut it up for tent guy lines or something. The dyneema is MUCH less stretchy, although I usually do have to clove hitch it onto a biner even to pull a fiddlestick at 300 feet.
