What everyone needs to remember is that this is just fishing. Fun, yes, relaxing, I hope so, world changing, not a chance. If you like flurocarbon and beleive it's better, then use it, but remember, others may not share your view point, and that's just fine. Remember, this is just fishing. Do you like furled leaders, great, use them and be happy. But remember, others may not share your views and that's just fine. Remember, this is just fishing. And one final thought - for several centuries people caught fish on horsehair leaders, and then they caught fish on gut leaders, and many of us caught lots of fish - even record fish - on nylon leaders that would make most of the people that use the modern stuff shake their heads in disbelief. The point is that there is room in fly fishing for the person that finds satisfaction in making and using furled leaders, there is a place in fly fishing for people that use tapered, knotless leaders and for those that prefer to 'roll their own." I can't repeat it often enough - remember this is just fishing.
