Natural Anchor Rope

Any feeling about using this rope to build natural anchors ...
I would like to use it with some tree anchors. I am thinking of cutting it in half to make it more manageable. I am under the impression that it is static enough to work well.
All the best ...
Thanks! - Keith

That will work fine. Cordolettes are only 7 mm. I don't think the dynamic aspect will make much difference.

If you plan on building slingshot anchors for top roping, find something static. Anything stretchy, like this rope, will saw over the edge and thus wear/cut through much more quickly.

If you're going to clip to it and belay off your harness, or off the anchor and rune the rope over the edge, it'll be fine.

Thanks ... I should add I already own this rope from some previous rigs and want to use it as I head upstate NY where there are some big natural anchors that need to be set up which is why I'm looking for length. I know safety should never be compromised, but I would like to NOT have to spend more money for new rope. I will probably protect the rope where it hangs over the edge with some tubing.

Any more ideas would be great.

If you don't want to buy a static rope just for this one trip, double or even triple up the 8mm twin (if you have the extra length) will reduce its stretch somewhat.

That will work fine.

You might put a piece or two of static line on your future shopping list. $0.85 per foot for 11mm static from REI. 30 or 40 feet is adequate and doubles as an anchor extender if you find yourself somewhere with anchors way back. That REI line is fairly supple which is what you want when rigging top rope anchors.
Guideline #1: Don't be a jerk.
