beyond recomended life, might your friends set up have the lines attached to far forward or aft on the topping lift causing
excessive chafe where mono exits plastic guide built into sail?
Have him contact dutchman at 203-838-0375, they are very
available and willing to spend time on the phone

helpful, knowledgable fellow last year when replacing my mono
but don't remember name.
cfarrar/Colin...excellent suggestion on the Dyneema
