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

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.
