A versatile fly line for mountain streams equipped with DTT Realized high buoyancy and weight balance that makes it easy to throw even at close range This custom-made stream line is equipped with the latest line manufacturing technology, Dry Tip Technology (DTT). It is designed to be slightly heavier at the front than regular lines so that it is easier to handle at close to medium distances, which is the actual fishing range in Japanese streams. It is also characterized by its smooth and delicate presentation. It is a standard item of Japanese stream lines that can be used stress-free from flat water in the midstream of Japan to mountain streams and headwaters. We also have a lineup of DWF, which combines the shooting performance of WF and the economy of DT.
