Cable replacement will never be any more convenient than right now. New
cables and sheave maintenance should set up long term tower use with little
attention.

Sell for scrap or replace the cable (with same or better cable and

and liability, if the cost of replacing the cable is LESS than the
expense
of any catastrophic loss and liability, replacing the cable is the way to
go. If you feel the cable replacement cost is too great, cut the cable and
remove it to prevent further use and sell the tower.
