The original model was Sam Shad who started as Balsa Lure more than 10 years ago. The body that almost followed the specifications made by balsa has turned into a lure that combines toughness and ease of use. Its unique flat form captures the medium range from shallow to lightly trace, up or up cross. The basic usage is steady retrieve of tight action. Furthermore, the body responds well to the rod work, it can move without inputting a large power, it creates an irregular dart action. We create a three-dimensional trace line from up cloth and cross, and further bring suspended trout to the byte by further suspending. There is a figure of a new mountain stream lure to drastically reduce the root risk and boldly attack it.
