Attica: Way back in the mid 1950 when anybody could buy from Wapsi. They had and sold a product called the Flutterbug.They are like what you are trying to do. I have three in my collection. They were very simple and the ones I have are tied with Marabou tails and are painted green with eyes on top of the leadhead. They have a nice wobble but are a lot longer lips than you have. The gentleman I got them from told me that they were one of Wapsi's short lived prouducts. Lacy Gee was a smart Businessman who went and found innovative people to produce product for Waspi. Some worked very well others did not. Next time you pick up your open wire bobbin thank old Lacy for bring that one to the market.
