Well my version of "an animal rig" is used on a margin pole (rigged with a fairly tight 16 elastic) for extracting carp from reeds/lilies and it's simply a small line through dibber fished on an 8lb line straight through to the hook.
It's really just a strong "hit & haul" rig,not a lot of finesse.
i do a bit of carp bashing 16/18 elastic carp hook 8 barbless . 10lbs braid small float use this in weeds /rushes when green as braid will cut through the weeds and get them out. will not cut when weed die off, just hold them and they saw through the weed by pulling back and forward
