Thin arms tend to deform and result in poor hook-setting, while thick arms struggle to transmit blade vibration to the body. The BT Spinnerbait Swagy resolves this dilemma. Its specially processed BT arm design gives the 0.95 mm diameter lower arm exceptional rigidity and resistance to deformation, while the 0.6 mm diameter upper arm efficiently transfers blade vibration throughout the body, creating a smooth, alluring skirt action. The head is made from a combination of tin and tungsten, with the high-density tungsten concentrated on the bottom. This ensures stable swimming even at high retrieve speeds such as gurgling and buzzing, and around cover it enables rapid recovery after deflecting off obstacles, reducing the risk of snagging.
