warm,
I'm NOT a saltwater man and I'm not sure about this knot w/flouro but I have found using heavy mono and the Non-Slip Loop it's a good knot for my uses and has really good strength from my own tests against the Perfection Loop.
Test it before you fish it though. I'm not used to really strong fish as you might be (me..just muskies and pike) but I have faith in this loop knot.
Jeremy.
