The standard dynamic mountaineering rope.
Static auxiliary ropes, e.g. rad line (which are sold for glacier use as well)
There is an article in the German magazine bergundsteigen that compares both types of ropes. That concludes having a static element is not necessarily a problem as dynamic ...
You're using a climbing rope, which is a dynamic rope, intentionally designed to be stretchy. (It's different from a static line.) So these properties are built into the rope already.
As in any climbing belay, the amount of stretch in the rope is a compromise. Too much stretch increases the chances that the person falling will fall too far and hit something.
Energy absorbers are used when attached to a fixed point, which you won't have access to on a rope team.
Additionally, the weight added to your base weight would further make this a bad pick to bring.
The Trango is a basecamping tent- large, heavy (twice the weight of the AC), it focuses on having lots of space inside to hang out in, to cook in. It's got lots of tie outs, you spend a bunch of time setting it up nicely. You'll want the Trango if you're getting to altitude then peakbagging.
The AC is the light, summit push tent. It isn't as warm, but it's ...
