The upper and lower lips of the crappie are fairly stout. It is the sides of their mouth when they have it open that gives them the name of papermouth.
The crappie that I hook in the floor or roof oftheir mouth I land. Many of those that I hook in the side of the mouth are on for about 15 seconds and then are gone. You will see a flash of silver, have the hit and then nothing. A crappie rolled onthe fly and you hooked it in the thin meembrane which tears very easily.
