Everyone should be prepared to chuck a chod out imo.
For a while everyone was using them but I don't think that's the case anymore.
Imo the chod can never be a "go-to" rig, too many flaws, but it can get you bites that no other rig can get so it's essential it is in your armoury.
I would use a safety bead on the top
I use Korda but yesterday I saw a company called poltergeist tackel sell the set up
maybe the guy who sells tackle here with the forum discount may be able to help
Chods are a great rig in the right kind of weed up until you drop a real big fish haven't really used a chod since i left KWP you can get one to sit nice on thick silk weed. Very easy for the fish to blow the rig at any point after picking it up though, very sharp barbed hooks are a must as big as you think you can get away with.
My preferred pop up rig that is a withy/chod style rig has to be the reverse combi.
I allways keep the cork stoppers from my single malt whisky bottles and trim to shape and use them for my chods. The carp in my lakes may be alcoholics.
Firstly I'd lead about the area where you pulled the bloodworm in from and hope to find "a spot" or better still "the spot". And also lead about other swims/areas you might intend on fishing into late autumn/ winter.
Failing that I'd happily put a chod anywhere. I know the way I set it up is safe so have no issues casting it anywhere.
