The rig has be posted with the wrong title it shouls read "How to tie a resetting ring rig"
The silicone re sets the rig into the correct position should the rig be picked up and ejected so it is perfectly set for the next fish. Most rigs do not reset if they have been picked up but as soon as you reel them in they reset. The only other rig that does not reset it self as a feature is the standard Knotless knot with a small peice of silicone to hold the hair on the bend of the hook. With this rig if you get a pick up the silicone is pushed from the bend of the hook all the way to the back of the knotless knot, thus indicating a pick up and ejection of the rig.
As with all of these things there is only so much that can be conveyed in still pictures and despite it looking cumbersome for me it has been devistating.
Thanks for lal your kind comments
