Heavy shock/bite tippet from the folks at Rio. Ultra hard, tough nylon that holds up to toothy fish!
This is the stuff that most of the guys around here use for Musky and also what we use for most of our saltwater applications when needed. We also use the 50lb and 60lb for butt secions on 12wt and larger fly lines. This is our "go-to" hard mono.
Rio heavy shock/bite tippet comes 60ft per spool.
40lb = .024"
50lb = .028"
60lb = .032"
80lb = .036"
100lb - .040"
