I am trying to connect 12lb leadline (lead removed for knot) to a 6lb flurocarbon leader but when I tie them with a double uni knot the flurocarbon breaks when pulling it tight.
I have tried a couple of times and it breaks with very little effort, I can't break the line without it being knotted.
I'm not too sure why it's breaking but it breaks at the part of the knot that is tightly coiled. Is there a better knot I can use with line this fine? I have used the technique of threading the fluro through the middle of the braid and tying an underhand knot on larger braids but it's too hard to thread with braid this thin.
I'm using sufix 832 leadline, and Seaguar blue label leader.
