Here's something I put together yesterday. It's 5" long and made of PVC. It sinks slowly and swims well, although I think an extra joint at the tail would make the action even better. Vodkaman gave me an idea for new hinges to use on the next one I make; this bait is so small that I had a hard time getting all the hardware and ballast in place.
I think I'll probably paint it in a baby bass or similar pattern, but any suggestions are welcome.
