One question i always ask myself, how can you get a bait to act and go into a carps mouth in exactly the same way as a free offering? but i keep coming back to, you can't, simply because your hook bait has alien objects attached to it.
I do wonder how sensative a carps mouth is to touch, i also had a mess around with rigs and worked on the idea of a bait moving up as naturally as possible, the problem is the bait is always attached to a hooklink, so even if the carp doesnt feel the hook, it will feel the hooklink. Its a tricky one but i do applaud your efforts fella. The one i came up with many years ago was a stiff boom of 6 inches onto which i tied a ring. The hook was tied in a normal fashion with braid of about 2 inches long, also with a ring at the end. The hook was passed through the ring on the stiff boom, this presents a nearly feel free rig, the only problem was, was how would i present such a rig so it would be effective enough to work properly. Its easier if i re tie the rig and show you with a picture to be honest, its a little hard to explain.
