New specs that can aggressively attack shallows."Slow Blatt Cast Up"! Which features a polygonal body that uses a Z light metal body with a lower specific gravity than iron, has achieved a compact silhouette despite its low specific gravity material. An outline that creates a stable flight attitude while maintaining a weight balance that is almost centered. The action tries to rise aggressively with respect to the input. In addition, the polyhedral body demonstrates three-dimensional turning performance. Even though the range of appeal is compact, it induces the target bite with overwhelming appeal. The specs that actively encourage the use of shallow surf even with high weight models are a proposal for a new stage that further expands the appeal of shore throw.
