Tied a bunch of these articulated NW Cockroaches on Spinnerbait wire this last winter. The wire weighs considerably less than a waddington and the hook cannot foul. It is also bendable like a wire leader. I used 32lb spinnerbait wire which is .013 thousandths. The small diameter wire is like having a stiff leader that is 4 to 5 inches long. It has about the same stiffness as 100lb tuna cord (fluorocarbon).
It also costs a fraction of the price of waddingtons.
I have used them for a few years now; the wire I get is stainless so I can use it in the salt as well. I usually cut off the pre-twisted eye and, using my vise and a pair of needle nose pliers, form a smaller - more traditional upturned eye. Another tip is to tie in a loop of backing or equivalent to attach the hook (hitch through the eye around the shank). This way if your hook gets dinged up on a rock you can easily replace it with out having to retie.
