I have 4 intermediate lines,all different colors.One clear,1 aqua,1 light blue/surf,and 1 cream colored glow in the dark.I fish these in the salt but no matter,the fish dont care.No one line fishes better than the others and im sure WW fish wont care either.I will say I prefer a colored line better than a clear just so I can see it and know where the line is in the water.
