I always fish a chod rig on a slack line. When I draw the rig out in my head when it is cast out and settled, I imagine the tight line to the lead. Where the rig sits in the main line, as jez says, around 12inches up; this would be off the deck putting the rig higher in the water than the 2 inch chod rig I have tied! Granted, fishing in deep silt this wouldn't be so prominent. Over light leaf litter etc though, and at short to mid range, I can't get past this feeling in my head!
