You can now match your trailer hook wire to your fly. Doubled over tests out at over 50lbs breaking strength and is stiff enough to hold the hook in position without fouling. Great for steelhead flies, increases hookups and numbers of fish landed! Senyo's Intruder Wire is also perfect for tying articulated streamers. Use as an articulation wire on jointed streamer patterns such as Galloup's Sex Dungeon, Circus Peanut, etc.
