My Favourite Fishing Knot.

          
This is my favourite fishing knot i use it when tying on my flies and spinners with flurocarbon, mono and copolymer, even attaching braid to swivels. It is a very strong knot but the main trick is to moisten the knot just before you tighten / bed it down and that way you prevent friction burn which is the main culprit in knots breaking.
