You want to make sure that when you start with a fresh reel of wire that the spool is full. Over time, cutting back and retying, shorten the amount on the spool and i respool once im below 700' or so. http://www.bloodruntackle.com/
When spooling wire I give the spool a wrap with electrical tape. I then attach 30# mono with an arbor knot and spool on 250 ft. (Okuma 30 series will require some "backing" to ensure the spool is full and the counter is correct). i then attach wire to mono using an albright knot and spool on 1000 ft of wire making sure i spool on as tight as possible by hand. On the business end the swivel is attached using a simple overhand knot. Before i use this newly spooled reel i attach a tripped diver and let out almost all of the wire and wind it all back on the reel under tension. Now its ready to be fished.
