Having fished for crappie in cold, clear winter conditions when they are lethargic and finicky, I can safely say that crappie don’t care what line you use. Other species tend to be sometimes and I use a clear mono leader big enough and long enough to get the job done. Here in FL where most of the water is stained to some degree, most every fish here is unaffected by the bright colored line. Used to use Stren gold years ago for LMB, brother used clear and scoffed at my line. He never did outfish me though.
Creativity is just intelligence fooling around
