P line fluoroclear is a copolymer monofiliment coated In fluorocarbon not actually fluorocarbon itself. Still good line and less stretch than typical mono. I use it myself on a couple bc reels because I feel like it gives me the best of both worlds as an all around general line. As far as loops on your Palomar knot I usually use a normal single wrap with copolymer.. but it being 20lbs test I'd do two.
