The new halyard came in the mail Saturday (6 days from ordering, 2 weeks ahead of schedule). Went back to the boat afer a day of sailing with my son and 2 grandsons to replace the old halyard. Got worried about 2 paper clips getting over the head sheave, borrowed some waxed whipping line from a slip neighbor and stitched the old halyard to the new one. I did end up using some rigging tape over the ends to keep them from separating. The line went over the head sheave without even feeling any resistance. Had a little trouble getting the stitched connection out of the mast slot, but with a little help from a winch...success! The new halyard works great. Thanks everyone for your advice.
