They are 30cm (12") lengths, perfect for standard waggler and feeder tactics, or trimmed down when used as part of a pole rig. B911 F1s are a fine wire version of the original classic B911. They are an ideal hook for shy F1 carp and quality silverfish. Tied to hi-tech, low diameter Japanese monofilament they are perfect for small expander pellets, maggots, casters and corn.
