Casting and carrying The 11- to 14-foot graphite rods, which start at $160, taper quickly to a tip far thinner and more flexible than that of even the lightest traditional fly rod. At the end of the tip is a short length of string to which the fly line is loop-knotted. Tenkara fly line is composed of multiple handwoven monofilament strands, making it light and springy. It unrolls, floats, and loops like regular fly line, but the design promotes less drag on the water and more stretch than traditional line. It lands like a feather and doesn't absorb water. Lines, which range in length from 101⁄2 to 13 feet, feature an end loop that lets you add a 2- or 3-foot piece of 4X or 5X tippet.
