I don't think that you have to go all the way down to a 2lbs leader. Remember that the waves and current add another variable that adds pressure on the line as well as the fighting fish. And who knows? You may "accidentaly" hook into a legal halibut while fishing for perch. It's been done before.

The lightest I go is 4lbs flourocarbon. I generally use a 6lbs flourocarbon leader and a 6lbs mainline, especially when the corbina are around. Good luck out there!

btw, I use a 10' crappie rod. You can cast it far if you need it, and it also helps to keep the line out of the water, thus preventing the waves from throwing your line around too much.
