It has been designed to fool the wariest of carp due to the extra stretch of the bungee elastic.. After studying the carp’s feeding habits at close quarters, this rig has been designed to fool them.. it is believed that a carp will pi ck up a normal hair rig and move the lead before ejecting it.. The bungee elastic put under tension will extend and drive the CARP TAFF HOOK downward to the bottom of the heavy lead weight, rather than stay in a fixed place and get ejected.. This will scare the fish, make it swim away and hook it even better.
