A new tricolor series equipped with a center of gravity movement system whose development has started with the main target of cherry salmon and satsukimasu in the mainstream. Three models have been added that have evolved the original model created with the concept of "faithful to the basics" into further development. The answers derived from the repeated test fishing were "just size", "+ α flight distance", and "+ α dive depth". Until now, I couldn't attack with the original model, such as "Because the flight distance does not increase a little, it does not reach the other side of the twist of the flow you want to pass, and because it does not dive a little, it does not reach the edge of the rock you want to touch." Eliminate blind spots. In addition, it continues to take action firmly without losing balance even in a violent flow, and the strong water push generated from the flat side body by the sharp wobbling roll action, and the blinking effect by the flashy flat hitting at the time of twitching attracts fish. I will.
