I've only been out with this rope twice thus far, so I can't speak to durability. However, I can say that the factory lap coil made the rope unkinked and untwisted right out of the package. The weight of it feels just right to me as well, making clips easy and effortless. It handles quite well and is certainly not stiff. Hopefully it ages well. Right now I'm extremely happy with it. Oh, and it has a middle mark!
