Fluorocarbon is notorious for slipping knots. The palomar will take care of this problem at the hook. I don't doubt the other knots that have been recomended will work also. The palomar is just the knot that I know and use.
Clinch knots are not good with fluorocarbon. Blood knots (essentially two clinch knots tied back-to-back) will also fail far too often with this material. Use a double or triple surgeon's knot with fluorocarbon instead of a blood knot.
