Thanks for the responses: The halyards aren't showing any excess wear (that I can see). Is there any way to check if they are binding to electrical cables or themselves without unstepping the mast? Is there a way to tell if the hole in the sheave is elongated without taking it apart; ie would it wobble a little when I spin it? I have no idea when or if the sheaves have ever been changed. There are two spare sheaves (one on either side of the ones currently in use) to which I could switch. Thanks again for the help. Michael
