I've debated that issue for years. Personally I hate flouro. I love braid I fished straight braid for years. I would switch to flouro sometimes but give it up. I'm not a leader guy because I hate the knot going through my guides. Right now I'm using Sufix Advantage mono for lower visibility than braid. That said I don't care what line you have you need to find fish that will bite. I've seen the same thing happen with straight flouro. You either need to find active fish or switch presentations. And remember even pros get skunked.
