It's wise to have a back up, most of the time it dont matter, but there are time's, it make's all the difference. I saw that, fishing with Tim Bagley , It got slow, and I could not catch one on braided line, and he was getting some on fluorocarbon, I picked up one of his pole's, that had fluorocarbon, just to see. And I hooked up right away. I had thought the same as other's, that it didnt matter. But there are time's where it does. I dont like those time's, when they seam to be smart and line shy. I think it's all about how they are feeding, if they are in a frenzy, braided is great, if not Fluorocarbon or clearer mono are the answer.
