I've got 27 pound leadcore to 12 pound mono backing, enough backing on there. I have em tied together with a 7 turn Alberto knot each way, with the lead pulled out of there and just the sheath in the knot. Just want to make sure that sounds good, is the backing poundage too light or ok, I'll play them lightly obviously. I see the copper guys use swivels on their connections in the reel.
