I've used a few brands of fluoro and they are more difficult to manage than mono's. They do tend to bed in with use and become more manageable over time. I was giving my leader a good stretch the other day as I find that it does behave better. I switched over to using pure fluorocarbon on my last trip as I was bait-boating the rig out but when I got home I took it off again! Using a leader does give you the benefit of a heavy invisible line near the rig but without some of the drama's associated with fluoro.
