Given the choice between having a very good fly line an average rod, or a very good rod and an average line, nearly all experts would choose to have the better line. And for good reason: the line is what actually carries the fly to the target and delivers it. If your line won't shoot through the guides, or float or sink as it should, or carry the fly properly, you'll have a terrible day on the water. Thanks to my fly fishing experience, I have choosen some of the fly lines I consider actually the best in the market.
