Hey Weedie,Mike is right what you need is a Flourocarbon which is almost invisible under water.There are a few different ones on the market depending on what your targeting ;)There is Vanish like mike said also daiwa TDR competition, Black magic, Platypus Stealth, plus many moreThe aim with lure/placcy's is to fool the fish which is why you should use a line which is almost invisible in the water.Cheers Adam
