I bouhgt a couple Curado reels at the beginning of the year, on one of the reels the drag keeps loosening by itself, not when I'm fighting a fish, but when not in use. By this, I mean, at the beginning of the day I check every drag on the po9le I pick up, so on this reel, I tighten the drag a little more then norm, then later on when I pick it back up, cast it, then check the drag again, it completley loose as a goose, it will happen more then once in a day. Anyone ever come across a problem like this, and there is anything I can do? Maybe just call Shimano?
