The ESP Cryogen Chod Rig is built for efficient hooking, using ultra sharp Stiff Rigger hooks, Stiff Bristle Filament, and a smoothly rotating Japanese Uni Link Swivel. The whipping knot on the rig grips the hook tightly, ensuring the Bristle Filament comes off the hook dead in line with the shank. The combination of the high-quality Uni Link Swivel and a subtle curved set to the Bristle Filament means that whichever way carp approach the hookbait, the rig spins round for a secure hook hold in the bottom lip virtually every time.
