Mono: Soft, supple, but stretchy, has high memory. Casts far but damages easily, absorbs water, gets twisted up. I like this for casting long distance topwater in clear water, or casting very small lures like small plugs, spinners, jigs. That is about it. Everything else FC does better. Especially for lures over 1/2 oz when casting is easier. Mono is a really bad choice for anything when you need to detect a strike and set the hook firmly, mainly plastics and crankbaits. It does better when you can visually detect a strike and don't have to set the hook through 20 feet deep of water. In other words- topwater and small panfishing gear. I like it a lot for casting, when it's fresh it just flies off the spool, can 50-60+ yards with certain lures. But it wears out quick, I usually re-spool it for every trip. FC: very stiff, it is like fishing with a wire directly connecting the bait to you, has amazing sensitivity. I swear I can feel even just a leaf of weed brushing by. Downside is it doesn't cast well at all, especially with small lures. It's a fantastic trolling line. I can tell by the way the rod tip vibrates whether the lure is running clean or has some weeds clung to it. The best part is it doesn't absorb water, doesn't stretch or retain kinks/twisting damage as much. So you can go a long time without changing it. Worst part is it costs about 3x as much as mono. But worth it! I can't stand fishing crankbaits and plastics without FC now. Braid: I don't really use it.
