"Spearhead Ryuki 70S & 80S" was developed with the concept of downcrossing the main basin of large and medium-sized rivers. The semi-long grip and flat, low center of gravity fixed weight design, which emphasizes water bite, provide high swimming performance that can handle strong and fast mainstream currents. The action starts quickly, and continuous twitching with rod work is also possible. The reduced body height prevents the cast feel from deteriorating due to the increase in body size, which is common with flat minnows, and achieves top-level casting performance in its class. The Ryuki 80S has outstanding long-distance casting performance comparable to models that move the center of gravity, and can capture large trout that swim upstream, such as cherry salmon and American trout.
