a chod rig will work anywhere, it is designed to, however once you have discovered what the bottom is really like then there are other more suitable rigs out there that will work too. I fish at a venue that is silty and have been using a small bag of boilies attached to the hook so that the bigger surface area stops them being masked by the soft silt. The lead is just heavy enough to get me the distance I need and ive wacked it with a hammer so it is flat and doesnt sink in as far. The hook length is simply 8 inches of supple braid tied in a knotless knot with no tubing, rings or fancy gubbins on it.
