I try not to constantly repeat myself.
Mostly because I've heard it....
But while you guys are going to smaller tippet.....I will mud my leader and go up in size......I get love from tough fish by hiding my leader.
3x will work with a loop knot. I may also use a sharpy brown/black to camo my tippet.
And we give ground....Run!
Between my experience pulling on tippet, and an intimacy with the rods I fish.....I haven't needed the "gum", but could see it if hunting just Walter Steelhead.
