What is the best 18 to 20lb fishing line for carp?
The best fluorocarbon line I’ve used is called “Vanish” By Berkley. It is 100% invisible underwater, very strong, smooth casting and never tangles on me. I only use 6-8 pound test and have landed 15lb salmon and 10lb trout on it with no problem and these fish are fierce fighters. As long as your drag is set properly you will have no problems. The invisibility of this line is unequaled. I’ve caught fish when no one else is simply because the fish cannot see the line, which is especially important if you are fishing highly pressured fisheries. I’m not sure if they sell it in the UK but if they do I highly recommend it!! Good Luck!!
