Only downside I've heard is that mono will tolerate a bit more stretch that Flouro. Flouro's more likely to break from heavy shock. I went back to mono leaders when fly fishing for steelhead. Typically swinging flies on a near straight line, and some of those fish hit like freight trains. Add in ones "set the hook" response to a hit, and I was breaking off fish.
