I have grown to size #6. #2 and #4 want hold my pants up anymore.
One nice thing about light line. If a giant green carp attacks your jig the line will break and spare your best pole.

I mostly use 4#, unless the water is murky or I'm right in the brush. I also used 4# when ice fishing for trout that averaged 5.5 pounds. All of the other ice guys would tell me that 10# is minimum for big trout through the ice. I would catch 20-30 fish to their 0-2 fish, and would very seldom break off. A real key was to use a very small sponge bobber that would barely support the bait, use zero weight, and also to leave 2.5 feet of slack line. The trout would make the line slightly quiver before ingesting and moving off. That's when to set the hook. Guys using the same bait and a sinker would never see the bite. If you fish for trout through the ice, give this a try. I guarantee you'll catch a lot more fish.

I completely disagree about nan-o-fil. Been using it exclusively ever since it came out. Granted you have a learning curve with it. However; once you figure it out, it's great. As far as knot strength goes, I use the uni to uni to tie the leader(4# Seaguar flouro) then I tie the jig with the slip uni knot. Have never experienced any knot failures. Have whipped several 8#+ bass and cats with it. Just gotta figure it out.
