Holographic tape. Inverted metal lip. I thought it would be cool to have a metal lip that you could work all different depths with, & sinks when you stall the retrieve. Its a bit more than 3oz. Have yet to test it out but heres the prototype. I have no idea how the design will swim.
It swims in a lazy S shaped pattern towards the surface in my head, maybe flutters as it sinks. But will stay at one depth @ the right retrieve speed.
