This has become a classic UKC thread, except no one has resorted to insults yet!
So, a whole load of people say it is fine. A whole load of other people say it is not fine. Some quote some source and could be wrong. Some don't quote a source and could be right.
How to proceed? Accept that the answer is not clear; decide if you want the nagging thought as you are above gear, decide whether the uncertain risk justifies taking the chance, consider your risk tolerance, budget and climbing activity to determine whether buying new ropes is the way ahead.
If you use them and fall and nothing happens, does that mean the replies that they are safe are correct? No.
If you decide to bin them and buy new, does that mean the replies that they are not safe are correct? No.
Your rope, your life tied to it. Your call!
