I seem to always use these three, depending on the rod and technique.

STREN Lo-Vis Green mono. 6LB test - jigging with my lightweight rod, which is mostly what I do, but some times I will troll with this.

Berkley FireLine 8LB test -trolling mostly, I seem to like mono more for jigging.

Berkley XT 10 -12LB test - sometimes I have a medium action Ugly Stick rigged with this for trolling.

If I only bring 2 rods its always the light weight with 6LB Stren and one of the other two, or sometimes both (I have a 3 self imposed rod limit). Deciding which to leave at home is tough.

One time I used my 5ft. Crappie rod rigged with FireLine for Smallmouth...that was fun.
