Considering these "patent infringement" issues, here's my thoughts for a Scrounger...1st there has to be some changes to avoid problems. Looking at a few commercial baits/lures (and available components), the Chatterbait can be imitated. Why not break out with a Hybrid for use in place of the Scrounger?
Head like the Poison Tail, or something more center-balanced or forward-balanced? Of course, there has to be a groove for the plastic "lip" that makes the head shiver/shake to give a Scrounger-like action. For the Lip, I think these should be made from the same material that the Original Scrounger Lip is (similar to clear water hose or tubing, such as what feeds the side-sprayer in Your kitchen sink), but make them shaped like a Chatterbait Blade...and sell the "Lips" by the 100 and 1,000...and a few different sized Lips, of course. The groove on each Head can be the same size (on all Head-weights) so the Lips only have to have 1 size mounting-hole, just offer different size Lips...this would also let You use different sized Lips on any given Head-weight, whether You wanted a little shake or alot.
