Re: Leader recommendation for 15-20lb Mi river Salmon
It's been years since I fished for Salmon here in Northern California. I don't know if the techniques are the same between my region and yours.
The norm was to used 12 pound test Maxima Ultragreen for dead drifting and 15 pound test Maxima for swinging.
As 2PawsRiver mentioned, heavier leaders can spook fish in clearer water. In that case, use a quality fluorocarbon leader. I'm partial to Seaguar fluro leader and tippet material due to better knot strength, abrasion resistance, and invisibility.
