At the UFT meeting last week, Lefty gave a short talk on knots. He's a big advocator of the Surgeons Loop. Says they are strong as anything. But you have to tighten them correctly, pulling out the slack on all 4 legs (2 legs being the loop itself). I've carried over Blod Knots from trout fishing but noticed I was the only one using them in the salt. So I've tied up some surgeon loops this year, I find it weird having bulky loops in the leader, but maybe I'll get used to them.
