You are much more likely to be able to pull an iron out with #30+ test (as long as you are comfortable being able to break that off). The San Diego Jam on the lure ring for sure. I am happy with the Trilene Knot for swivels and hooks. Lube the line before tightening knots and retie any knot that does not look or cinch up good.
