The weakness of tungsten bullet sinker, rough workmanship inside the line hole, was resolved with Space Metal on the Zappu Bullet Shot , which has made a precision molding possible, while maintaining sensitivity. Zappu added a dip at the tip to keep the sinker stopper in place. The tiny 1/32oz performs great with ultra-light Texas.
