Twin Dancer hooks are to improve catch rate for trout. With the Twin Dancer hooks, spoons work better with less dragging from hooks. Hooks are tied with soft braided leader allowing spoons to move more freely. AND, Twin Dancer hooks also reduce hook-offs after they hooked on fish. Single hooks penetrate jaws deeper than treble hooks, and the flexible leader keeps hooked at jaws.
This TD-33R has red medium-wire hooks, great for 3-8lb test lines.
Best matching, L for 3-5g, LL for 5-8g, 3L for 8-10g.
