My line failure with Vanish wasn't at the knot and wasn't abrasion related. I came up with half a leader for no good reason three fish in a row. I am suggesting that it's wet breaking strength is ridiculously low.

This was several years ago when it first came out, maybe it has changed but I am not willing to give it another shot.

I have a question for you, Dave ( or anyone). I cannot think of a reason necessitating zero visability mainline. Why would you use flourocarbon mainline for salmon or steelhead?
I would choose straight mono or a smaller diameter braid with zero stretch over flourocarbon anyday.

Just curious.
