I wonder what action this product would have in the water. If you look at a sea lice pinned on a hook anchored to a sinker, it tumbles mostly due to the water movement, with probably thousands of diff actions until it is eaten by a fish.
Probably would fish it in a similar fashion, ie a fixed sinker or have it weighted in such a way that it sticks very near to the bottom,or on the bottom bouncing along the sand with extremely short movements.
Did you manage to get hold of any and did you have any results with them?
