Re: Leader recommendation for 15-20lb Mi river Salmon
This is not a question of fish but of fly. The heavier the fly the stiffer the leader needs to be to 'turn it over'. For a heavy brass tube I would think nothing of using 25lb but for a light Size 12 double for example I may go down to 12lb (but never below this for salmon). The norm for me is between 15 and 17lb clear fluorocarbon. I personally never use coloured mono. There is absolutely no reason for going too light!
Hope this helps
