I like the Seaguar Abrazx fluorocarbon, I use both 12# and 15# test. 15 is easier to see and a little stronger, but 12 is easier when tying knots of course. Cray turned me onto this line a year and half ago or so and I haven't used any other line since for rigs. It's durable and strong as all get out, a bit costly but a spool will tie a whole lot of rigs. P.S. not a fan of tying rigs with braid myself..
