In reply to Sully:
There will be nothing wrong with that stuff at all if it's been kept out the sun.
There's plenty research on old ropes, nothing wrong with them.
One of my ropes is 15 years old, don't use it much now as I have others, but have no qualms about using it sometimes.
The sheath protects the individual strands.
Obviously any visible damage replace it.
Some of my crabs were bought second hand from a lodge instructor 32 years ago, just abbed off one in France a couple of weeks ago when it rained.
Some of my friends are the originals, although I replace the slings every 5 years or so.
