Stillwater Blue I think came close enough so its time to spill the beans.
Here are the two rigs created by Martin Clarke. The Scorpion and Snake rigs. The idea is that only the hook, not the bait, is taken into the fishes mouth. I have my doubts on the practicality but they are certainly ingenious & Martin claimed to have caught a number of large fish using them.
Me neither. But Martin said he caught a number of big fish using them.
I get the feeling that although they may catch fish it may not be in the way envisaged. I can imagine a large Carp taking both bait and hook into its mouth all in one go rather than the rig working as the diagrams show.
