Re: Drag on a fly reel
The drag is also negligible depending on what you're fishing for, and even how you fish to some extent. Certain fish will rarely make runs great enough to put you on your reel.
I primarily fish for largemouth and my reel does little more than hold my line. I am able to play the fish entirely by holding the line in my left hand and letting out excess stripped line if the fish begins the pull.
Some people like to use the reel regardless of their target species, and take the time to reel in all slack and stripped line before they begin playing a fish.
