Trust you Sandy.....
Not wetting Copolymer was something I learned somewhere, cant remember where to be honest, but I have just run a google and found this:
To Wet The Knot Or Not?
One of the more enduring myths, sadly perpetuated in the fishing books, magazines and videos – still being published today – is the ‘wet your knot’ myth.
When mono lines were first introduced, they were thick and stiff. The line surface was, by today’s standards, very rough. Theory, (and it is just a unproven theory), was and in many cases still is, is that pulling a knot up tight built up friction and hence heat.
Heat is a line killer. It reduces line strength markedly. Trouble is there is no evidence that pulling up a knot tight builds up anywhere near enough heat to damage the line.
Modern lines are more supple and thinner for similar breaking strains. They form into knots much more easily. The surface of modern line is very smooth, and has very little friction quotient.
It is because modern lines are thinner and more supple that you should not wet your knot – here is why.
The best method of tying a knot is to tie the knot carefully, ensuring there are no hidden line cross-overs. Then pull the knot up tight, slowly but firmly, allowing the twists to form-up properly. If you wet a knot there is a distinct danger of forming what is called a ‘liar’ knot.
A ‘liar’ knot is a knot that has not formed properly.
It looks the part, but its appearance is deceptive. Saliva allows the twists and turns to slide over themselves as the knot is tightened. Deep within a liar knot a piece of line has crossed over another piece. This will act like a scythe when the knot is jerked tight.
Tie And Re-Tie
A knot, any knot, is the weak link in the fishing system chain. Any knot reduces the breaking strain of the line, when it is first tied. Hook into a couple of good fish and the knot reduces the breaking strain further.
Fishing line is designed to achieve maximum strength in a straight pull. A knot by its very nature changes the direction of the pull. Each pull on the line reduces line strength at the knot.
It is a pain, especially in the midst of a good bite, but it is good practice to re-tie knots after landing, or losing a good fish. This is especially true when fishing lines of less than 10 kilo breaking strain. It is imperative to re-tie a knot that has secured any part of your terminal tackle to a snag to line-breaking point.
Just as important is to re-tie all knots before starting fishing. A knot left tied from the last fishing trip is a time bomb waiting to lose you the fish of a lifetime.
