I am attaching fluorocarbon to braid...I am currentlyt using a "blood" knot...but Ive heard that the uni-knot and the seaguar knot is better...The blood knot works good for me on my dropshot rig, tying 6lb Berkley 100% to 20lb braid(6lb diameter)..but Im wanting to start using on my heavier applications, like my jig rod where I use 15lb Berkley 100%...is the blood knot strong enough for this?...if not, what is? Thanks!
