I bought a Shimano Stradic 2500 fk brand new and have had it for a year. When I pull line off the spool with the bail down on minimum drag the reel slowly tightens the drag as more line is pulled off the spool until the reel is at max drag. I checked in with Shimano and asked for a warranty claim and found that my reel was too old to make a claim on. I was wondering what I should do to resolve this issue with the reel, would it help if I bought Carbontex drag washers and replace the drag washers already in the reel?
