Nitlon 10, 12 and 16lbs
Nitlon seems to have a harder outer, I was using Rock FC before also Famill. I found that my Mainline ( Castaway ) was cutting the leader material at the Braid to leader connection. Tried several different knots..Allbright, Impro All, Uni, Mike Connolley, 5 Turn with and without a Bimini Twist with no joy.
Tried Nitlon and now use either a Mike Connolley or Improved Allbright, If i get a snag the leader now breaks at the Jig
