WHY is the Chod Rig so EFFECTIVE?

Rigs over the years seem to follow fashion and the Chod rig seems to get little publicity these days. But the Chod Rig is so effecfive in terms of its ability to catch a carp on almost any bottom. This time of year the carp love to hold up in and around the dying weed and I can't think of more versitile presenation than the Chod, plus you can almost guarantee it's always presenting well enough for a bite! Yes this rig seems to have dropped out of fashion but you can see here just WHY it's so effective.....
