Wouldn't have thought loss of strength due to UV would be of any significance on a piece of 10mm dyneema rope (not thinking of climbing slings). It has a massively over-engineered breaking strength, stuff's used on ships for heavy duty work. But yes it would lose strength from its as-new rating. The abrasion against rock would be more of a concern but again not thinking about climbing slings here.. tightly-woven dyneema rope is pretty indestructible unless chopped with a blade. I expect it's already been done, but it would be easy enough to put Dyneema on a test-bed exposed to the harshest possible UV to gauge loss of strength over long time periods.

How does this update reflect on seaside crags in N Wales, Gower, Swanage, Aberdeen etc?

Was Edwards approach the three adjacent drill holes to form a cam slot?
Just leave the holes empty and carry a rack of Coeur Pulse.
