We pick our spey lines partly because of the circumstances of a certain location, but also because of our preferences in timing and rythym. The first time you successfully cast a mini-skagit head out from under the briar patch at your back is a revelation. The first time you realize that you can pick up 90 feet of long belly line with your 16-footer is another kind of revelation. Casting concentrated weight is a kind of mechanical efficiency, and a skagit line is far down the continuum toward the ultimate in concentrated weight: a baitcasting rod with a heavy sinker or lure. Stretching the weight out over more feet allows us to enjoy the rythyms of how the casting stroke harmonizes with our minds and nervous systems. (It's like sex: sometimes you want it to last two minutes, sometimes two hours; but most of the time we're best served with something in between).
