The answer to all your problem!!!
I use suffix performance braid, 10 pound strength with a 4 pound test diameter, you can't go wrong with this line, it is alot stronger that what it is rated at, it is super sensitive, you can feel a crappie thinking about biting, it works great on a spinning reel setup for casting also, and because it is such a small diameter it does not bother the crappie at all. It has so many advantages over mono or flouracarbon.
try it on one rod before you switch them all to it, it takes some getting use to but it is the answer to all line questions and problems. It is suffix performance braid 10/4 it has gore tex fibers woven into it, which gives it awesome tensil strength, and gore Tex is water proof so your line does not soak up water, it also slows the fall of heavier jig heads due to the bouyancy of gore Tex. Slower fall keeps the bait in the strike zone longer.
