Holding the line from your reel in one hand, allow the reel to hang freely. At a very light drag setting, the reel should descend slowly and evenly to the floor. If the reel won't drop slowly of its own weight against the drag, loosen the drag a little more. The reel's descent should be slow and even without any hesitation or unevenness. If the reel hesitates or descends jerkily, your drag needs work. In that case, you can either ignore the problem (which I confess to doing sometimes) or fix it.
