What kind of long rope? Like...what are we talking about distance wise? Long rope here the standard is PMI EZ Bend Pit Rope, or the basically same thing but cheaper, Highline Flex. Highline used to be PMI Canada and when things changed "Danger" kept the PMI equipment and started Highline. Highline rope is prettymuch made for caves (cheap but great!) as manufacture rules are different up there, a tracer is not required, which allows it to be produced quite cheeply. It's something in the range of $0.40 a foot. Same high abrassion resistance, I prefer the flex version which is as it sounds, fast flexible rope, but they have become famous here for their stiff rope, which is stiffer than PMI MaxWear, it's a friggin' cable. Anyway, all of it is very low stretch! Elongation: 1.6% at 300 lbf | 3.1% at 600 lbf | 5.3% at 1000 lbf makes a huge difference in how much "climbing" you have to do just to get off the ground!
