The main cord we use is zing it or lash it 1.75mm we use it because we use tarp flyz and Dutch hooks. Amsteel is used for hammock suspension because it can carry such heavy weights and it is over kill to use it for ridge line. That is the same with dynema. Those are used by whoopie slings also because it is so easy to splice. Zing it is used for ridgeline it cannot hold as much as Amstel but it does the job.
