Speaking of shapes, it crossed my mind that I may try this:

You could make it slimmer/taller, with/without a head, etc, as you like. I think this shape has the advantade that you can place the weight at the lowest points of the lure. I wonder it this shape has been tried before?
Another idea came to my mind after seeing Luretrekker's "winner" (the lure which produced a nice pike for him). That lure has a scar on the nose, and I think it does not come from a pike, but rather from the encounter with rocks or gravel, or similar. I think I could make a protective cap for the nose, using clear plastic sheet, which you could wrap around the nose using heat. Just an idea.
So Diemai & Luretrekker, this is all your fault:angry:
Rofish the link you posted looks very much like a Heddon Cousin lure
you carve it & let us know the action please.
