Webbing has always been what I use for making anchors in canyons. The reason I bring up this discussion is because of a recent first decent. Long story short, I had some miscellaneous gear that I put to good use for this canyon. I had a 300' 8mm Imlay rope that due to core shots I had to cut down to 200' I had a 200' 9.2mm Imlay Canyonero that due to the same I had to cut in half. Each of these ropes had plenty of lengths that did not have core shots, so usable for sure. We made anchors with these lengths for several drops, which prompts me to ask you guys, is there a big difference between webbing and rope for making anchors? I am not concerned about the breaking strength, but more about the durability to the weather. Webbing tends to be nylon, and in my case the rope was 100% polyester, so how do these materials differ on weather exposure? If you see an anchor with rope instead of webbing, would you be inclined to replace it with webbing?
