I tend towards the minimalist school of thought, but I think the incredible variety of fly lines is great! I'll never need or use most of them, but part of the beauty of fly fishing is that we can make it as simple or as complicated, as narrow or varied, as we want. For some people having only a few basic choices would suck some of the joy out of it, and no one wants that. Personally, I just find a line geared towards the majority of my fishing and stick with it. All told, I probably like Cortland 444 best. My cardinal rule is, avoid the cheap, avoid the hyper-expensive. Cheap is rarely a bargain, and hyper-expensive is overkill (for me).
A right emblem it may be, of the uncertain things of this world; that when men have sold them selves for them, they vanish into smoke. ~ William Bradford
I finally realized that Life is a metaphor for Fly Fishing.
