I am not a line snob or scientist. I have used Mr. Crappie 6lb line for many years now, for jig fishing, or minner fishing. I have nothing bad to say about it. The only time I don't use it is in extremely thick cover or sharp rocks. I have poles set up with spider wire 15lb braid for that situation and it works great. I do however, use a fluorocarbon liter of 6lbs tied to 10 Mr. Crappie line when I troll. Seems to work for me. And none of it is very expensive. Not sure if that helps or not. Good luck to you.
