In the good old days before there was a reel for every size line and most were built to handle a DT8 The simple thing to do was to fill the spool with store string to a point you could put 100yds of backing over the top add the line and be set. some folks would glue cork to the spool and use that as a filler. both worked well. But back then.... Thats close enough was ok with most fisherman and you were never looked down on for close enough. MY HOW TIME HAVE CHANGED.
