So I'm trying to lighten my group's climbing load for a technical climb we're doing on Rainier. I'm already going to have some quickdrawed slings in our rack for the ice screws/pickets/rock pro. However, for glacier travel I've always preferred having the ability to make prussicks for any emergency hauling system, rather than using a Klemheist or Autoblock knot.
I know that nylon webbing has better shock absorption than climbing cord, but I'm wondering how big of a difference it would make for use on pickets & ice screws on 40-50 degree terrain, as I'm tempted to use cord for some (but not all!) of my alpine draws.
Any thoughts?
