I use whatever I find on sale. It's just crappie. Unless you are trying to catch a world record or fish the "trophy lakes", I don't think it really matters. The only line that I know really sucks is Vanish. It was one of the first fluorocarbon lines and the worse. I use 6lb. Hi vis, camo, and clear. When I get tangled long lining, I know which line goes where. Makes it a lil easier. I do use a fluorocarbon leader on all rods though. My lake is VERY clear and I think It helps, especially when shooting docks. I just tie a triple overhand knot to connect leader to main line. Just like a regular loop knot, just no loop. Caught stripers with no problem.
