Good info here. If you see tuna in the area and you aren't getting bit, send the baits further back and consider down-sizing the fluoro leader. The leader size can be much more important than you would ever believe.
Ccab, I see you are in Addis. I live in BR now, but grew up in Plaquemine. Shoot me an email and we'll talk.
