I got a spool of the 6mm after a failed attempt on the Palisade Traverse (8 mile technical ridge traverse on delicious Sierra granite). There is very limited information on the route and we soon found ourselves realizing we had a lot of mandatory rappels ahead of us and not enough cord to set them up. We ended up bailing to the east and had to sacrifice a number of our good slings to get back to the glacier. I haven't made it back to the traverse yet but the spool is getting used a lot in making cordelettes and replacing tat at rappel anchors. If you are going through cord at a steady rate getting a spool is the way to go from a cost and convenience perspective.
